摘要: A multi-band antenna comprising a device which is capable of functioning during at least a lower frequency band of operation and at least a higher frequency band of operation. The antenna comprises an elongated radiating element having a helical radiating element connected to one end thereof with one end of the helical radiating element being received by a non-conductive insulator. An outer conductive shell embraces the non-conductive insulator and at least partially encloses a portion of the helical radiating element. The straight radiating element acts as the antenna radiator during both the high and low frequency bands of operation.

摘要: A retractable antenna for use with a cellular telephone wherein the retractable antenna is removably mounted on the upper end of the telephone. The retractable antenna includes an antenna housing which extends upwardly from the upper end of the telephone and which has a matching circuit provided therein. A helical radiator is positioned in the antenna housing and has its lower end operatively connected to the matching circuit. An elongated radiator is selectively vertically movably positioned in the antenna housing and the telephone and is movable between extended and retracted positions with respect to the antenna housing and the telephone housing. The lower end of the elongated radiator is electrically connected to the upper end of the helical radiator when the elongated radiator is in its extended position. The elongated radiator is electrically disconnected from the helical radiator when the elongated radiator is in its retracted position. The matching circuit in the telephone housing is operatively electrically connected to the telephone circuitry so that the antenna serves as a 1/4 wave antenna when the elongated radiator is in its retracted position and so that the antenna serves as a 1/2 wave antenna when the elongated radiator is in its extended position.

摘要: A retractable antenna for use with a communications device such as a cellular telephone is described and which may be moved from a fully extended position to a fully retracted position with respect to the telephone housing. The telephone circuitry utilizes a matching circuit to match a high impedance when the antenna is in the extended position. When the antenna is in the retracted position, it changes from a series resonance circuit to a parallel resonance circuit so that it may match the low impedance.

摘要: A diversity antenna comprising two planar inverted F antennas (PIFAs) characterized by: two radiating elements with or without the physical separation between them; the spatially separable radiating elements of the two PIFAs with side-by-side or orthogonal placement with respect to each other are combined to form an equivalent single element consisting of the composite assembly of two radiators; a small ground plane of rectangular or L-shape with or without bending at its opposite ends is common to both the radiating elements; the radiating elements are placed above the unbent common ground plane; the radiating elements are placed above the vertical sections of the bent common ground plane; the shorted ends of the spatially separated radiating elements are placed back to back on the said common ground plane; a common shorting post placed along the common boundary line resulted by the merging of the two radiators with a prior side by side mutual placement; a common shorting post placed within the common boundary surface resulted by the merging of the two radiators with a prior mutual orthogonal orientation.

摘要: A Planar Inverted F Antenna (PIFA) is disclosed comprising a radiator assembly positioned in the interior of a lower Radome member. An upper Radome member is placed over the radiator assembly with the upper Radome member and the lower Radome member fully enclosing the radiator assembly. The radiator assembly is held to the upper and lower Radome members by means of three dielectric blocks on each member. The radiator assembly comprises: (1) two radiating elements placed on the opposite sides of common ground plane; (2) two separate shorting strips extending between one end of each radiating element and one end of common ground plane; (3) a common feed conductor in the form of a single strip connecting one edge of each radiating element and the common feed conductor which has a disc-shaped portion with an opening formed therein. A ground tab is formed as an extension of the common ground plane. A hollow cylindrical structure formed as an outward extension of the lower Radome member constitutes the embedded (built-in) connector for the PIFA. A metal rod is inserted through the opening in the disc-shaped portion and protrudes into the hollow cylindrical structure to serve as the feed (center) pin of the embedded connector. A cylindrical dielectric block on the bottom surface of the upper Radome member holds the feed (center) pin in the designed location of the embedded connector. The ground tab protrudes into the hollow cylindrical structure and maintains a flush contact with the side wall of the hollow cylindrical structure to provide the ground potential of the embedded connector.

摘要: An antenna is provided for a wireless communication device such as a handheld radio or cellular telephone. The antenna may be either embedded internally in the transceiver or may be mounted externally thereof. The antenna comprises a pair of 1/4 wave radiating elements which are coupled out of phase to create an end fire bi-directional pattern for the antenna. The radiating elements are attached to a micro-strip transmission phasing device which is comprised of a center conductor, a ground plane and a substrate material. The micro-strip transmission phasing device supplies a zero degree to one hundred eighty degree phase shift from one radiating element to the other radiating element.
