    摘要: A wireless apparatus (such as a wireless microphone) utilizes an antenna comprising at least one element, which also supports a mechanical feature, an electrical circuit feature, or an ornamental feature. When an element is incorporated into an antenna, the element also continues to support its original feature. Embodiments may support different antenna types, including a half wave dipole and an inverted-F antenna that may be configured at different frequency bands suitable for Bluetooth® and WiFi® services. Embodiments support a wireless microphone that utilizes an antenna comprising a grille assembly and a chassis housing, where the grille assembly and the chassis housing are separated by an electric insulator. The RF output of a transmitter is electrically connected to the grille assembly while a grounding point of the transmitter is electrically connected to the chassis housing.

    摘要: A dual band antenna that allows the independent optimization of each frequency band by adjusting the sizes of the antenna elements. For example, an antenna may have two different drivers, one for the high-frequency and one for the low frequency. By using elements orthogonally connected to the low frequency driver, the low frequency driver can function as both a reflector to the high frequency drivers and the low frequency driver without affecting the antenna's performance in the high frequency. The antenna may also have parasitic elements. For example, parasitic directors parallel to the high frequency band driver can be configured to improve performance in the high frequency band. Pairs of additional parasitic directors can be orthogonally connected these directors. These pairs can be adjusted in size to improve performance in the low frequency band with minimal impact on performance in the high frequency band.

    摘要: An RF distribution system distributes a radio frequency (RF) signal to a plurality of receivers. Ports provide RF connectivity from the antennas to the receivers while also providing data connectivity between the receivers. Sensors detect which receivers are connected to the distribution system so that the distribution system can route data from the first detected receiver to the other detected receivers and back to the first detected receiver. The distribution system can dynamically alter the routing if the receiver configuration changes. Consequently, a receiver can send data to other receivers through A-ports and B-ports of a radio distribution system. The A-ports provide RF connectivity to a first antenna while the B-ports provide RF connectivity to a second antenna. Different commands for locking, unlocking, scanning RF spectrum, and configuring can be sent between the receivers via the A-ports and B-ports through the RF distribution system.

    摘要: Slotted planar inverted F antennas are provided that can be operated in multiple frequency bands and are usable with electrically small ground planes. The antennas may have multiple planar levels and the impedance of each level (corresponding to a particular frequency band) may be independently adjustable. The antennas may have a self-supporting structure that does not require a separate frame. The antennas may further have a right hand circular polarization hemisphere and a left hand circular polarization hemisphere. Multiple antennas may be situated orthogonally to one another without adversely affecting their performance, due to the hemispherical polarizations, and thereby provide polarization diversity. The number of antennas and associated components used in wireless communications devices may be reduced by using the antennas, as well as reducing the amount of space needed for the antennas.

    摘要: An antenna assembly for a wireless apparatus (such as a wireless microphone apparatus) comprises two inverted-F antennas. The antenna assembly may be formed from a single stamped sheet metal piece to facilitate manufacturing, which may allow the relative orientation of the two antennas to be reliably maintained. Moreover, manufacturing of the wireless apparatus may be simplified since one antenna assembly rather than two separate antennas may be connected to a printed circuit board of the apparatus. The two inverted-F antennas of the antenna assembly may have a common grounding element that joins the two inverted-F antennas and connects the two antennas to a ground plane of a printed circuit board, where the grounding element of the antenna assembly may be shaped to accommodate a corner of the printed circuit board that the antenna assembly is mounted to.

    摘要: A wireless microphone system comprises system equipment (for example, rack-mounted equipment including receivers/transceivers, distribution amplifier), one or more transmission line accessories, and a transmission line network connecting the accessories with the system equipment. The transmission line accessory compensates for downlink RF losses on transmission lines between accessories and between an accessory and system equipment. Compensation parameters for the transmission line accessory is determined by the system equipment by generating an uplink RF test signal by an RF source at the system equipment. The RF source may be varied over a plurality of frequencies to determine the compensation parameters over the plurality of frequencies. The system equipment subsequently instructs the transmission line accessory to configure an adjustable RF gain circuit (and also possibly a compensation filter) accordingly. The wireless microphone system may also discover accessories on the transmission line network to facilitate installation and maintenance.
