Abstract: A wireless terminal having antenna diversity comprises a transceiver coupled to a plurality of antenna feeds and a ground conductor (902), the antenna feeds being coupled directly to the ground conductor (902). In one embodiment the ground conductor is a conducting case (902). The coupling may be via parallel plate capacitors (504) formed by a respective plate (506) and a surface (908) of the case (902). The case (902) acts as an efficient, wideband radiator, eliminating the need for separate antennas. Slots (912) may be provided to increase the radiating bandwidth of the terminal and improve its diversity performance. Good diversity performance is obtained in a range of environments, whether the terminal is hand-held or free-standing.

Abstract: An antenna arrangement comprises a patch conductor (102) supported substantially parallel to a ground plane (104) and a feed conductor (106) connected to the patch conductor. Such an arrangement is similar to a conventional Planar Inverted-F Antenna (PIFA), but lacks the additional grounding conductor connected between the patch conductor and the ground plane in known PIFAs. Elimination of this grounding conductor enables matching to be performed by external circuitry, thereby enabling a better match to be achieved and enabling similar performance to conventional PIFA antennas to be achieved from a reduced volume. These advantages are particularly apparent for dual-band (or multi-band) operation, where the use of a dual-band matching circuit allows a much smaller and less complex antenna to be used.

Abstract: A wireless terminal a transceiver coupled to an antenna feed and a ground conductor (502), the antenna feed being coupled directly to the ground conductor (502). In one embodiment the ground conductor is a conducting case (902). The coupling is via a parallel plate capacitor formed by a respective plate (506) and a portion of the surface of the case (502).

Abstract: An antenna arrangement comprises a patch conductor (102) supported substantially parallel to a ground plane (104). The patch conductor includes first (106) and second (108) connection points, for connection to radio circuitry, and further incorporates a slot (202) between the first and second points. The antenna can be operated in a plurality of modes by variations in the impedances connected to the first and second points. For example, if signals are fed to the first point (106) then a high frequency antenna is obtained by connecting the second point (108) to ground and a low frequency antenna by leaving the second point (108) open circuit. A wide range of embodiments having alternative connection arrangements are possible.

Abstract: An antenna diversity arrangement is applicable to frequency hopping receiver (34) for receiving data packets transmitted on frequency channels lying within an overall frequency bandwidth, divided into a plurality of sub-bands. In each sub-band the frequency characteristics of the channel will be substantially the same. The choice of antenna (10, 12) for a particular sub-band is done by carrying-out frequency diversity measurements and the selection is treated as being valid for a period of time which may be preset or determined dynamically. In operation the hopping sequence is known to the receiver so that it can determine in advance the frequency of the next data packet to be received and can select the particular antenna without the necessity of carrying out diversity measurements. At the end of the time period the suitability of the selected antenna is checked and if necessary the selection is updated in the receiver.

Abstract: An antenna arrangement (300) comprises a ground conductor (102) on which is mounted an antenna (304). The antenna is small relative to a wavelength at operational frequencies of the antenna arrangement (300) and the dimensions of the antenna (304) are selected so that the combined impedance of the antenna (304) and ground conductor (102) is suitable for driving via a conventional matching circuit. This condition is met when the bandwidth of the arrangement is dominated by that of the antenna and ground conductor, rather than that of the matching circuit. In one embodiment the antenna is a triangular conducting element which is considerably wider than its height, the length being sufficient to to give a reasonable resistance and the width being sufficient to reduce the reactance to a level that can reasonably be matched.

Abstract: An antenna arrangement comprises a patch conductor (102) having a feed conductor (106) connected to a first point and a grounding conductor (108) connected between a second point and a ground plane (104). An example of such an arrangement is a conventional planar inverted-F antenna. A problem with such antennas is that their impedance is inductive, making them difficult to feed. The present invention incorporates a slot (702) in the patch conductor (102) between the first and second points, which enables the inductive component of the antenna's impedance to be substantially reduced. Suitable positioning of the slot (702) on the patch conductor (102) also enables an impedance transformation to be achieved. The antenna described above may have a substantially reduced volume compared with known planar antennas with minimal reduction in performance.

Abstract: An antenna arrangement comprises a patch conductor (102) supported substantially parallel to a ground plane (104), a feed pin (106) connected to the patch conductor at a first point and a ground pin (108) connected between a second point on the patch conductor and the ground plane. The feed and ground pins are connected by a linking conductor (510) and have shunt capacitance means coupled across them. Suitable values of the capacitance means and the location and dimensions of the linking conductor enable a good match to the antenna to be achieved. The linking conductor may be directly connected to the patch conductor or there may be gaps between the feed and ground pins both above and is below the linking conductor. An impedance transformation may be provided by the feed and ground pins having different cross-sectional areas and/or by the provision of a slot in the patch conductor.

Abstract: A radio communications device, such as a mobile phone or Bluetooth device, comprises a ground conductor (302) incorporating a slot (304) and means (308) for coupling a transceiver to the slot to enable the ground conductor to function as an antenna. Such a device enables efficient radiating performance to be obtained from a significantly smaller volume than known antenna arrangements. In one embodiment the ground conductor (302), slot (304) and transceiver are integrated in a module (206), which module is adapted for connection to a further ground conductor which provides the majority of the antenna area. The further conductor would typically be a printed circuit board ground plane or mobile phone handset. Matching and broadbanding circuitry may conveniently be incorporated in the module. By varying the area of the connections between the module and the further ground conductor, the resonant frequency of the slot (304) can be modified.

Abstract: A transceiver for use in a time division radio system comprises a transmitter (104) and a receiver (106), each coupled to a different port of an antenna (102). By suitable switching of low impedances between antenna ports and ground, signals can be routed as required between the transmitter, receiver and antenna. In one embodiment the antenna (102) is a folded monopole which is fed at one end while the other end is grounded by switching the appropriate circuitry (114,112) to a low impedance state. In a modification of this embodiment one switch (114) connects the antenna (102) to a DC supply (Vc) which provides power for the transmitter when the transceiver is functioning as a transmitter. Filtering and matching circuitry (502,504) can be inserted as necessary between antenna feed lines (108,110) and the transmission and reception circuitry. In alternative embodiments the antenna may have further ports, with impedance changes at these ports implementing the switching and routing functions.
