摘要:
A mobile wireless communications device may include a portable housing, at least one wireless transceiver carried by the portable housing, and a satellite positioning signal receiver carried by the portable housing. Moreover, a satellite positioning antenna may be carried by the portable housing. The satellite positioning antenna may include an active element connected to the satellite positioning signal receiver, and a passive element connected to a voltage reference and positioned in spaced apart relation from the active element and operatively coupled thereto for directing a beam pattern thereof.
摘要:
A mobile wireless communications device has a portable handheld housing. A circuit board is carried by the portable handheld housing. RF circuitry is carried by the circuit board. A diversity antenna and main antenna are carried by the portable handheld housing and coupled to the RF circuitry and operative together. The RF circuitry tunes the diversity antenna into a diversity communications frequency band to achieve a diversity mode of operation with the main antenna and tunes the diversity antenna into a non-diversity communications frequency band when cross-coupling has occurred from the diversity antenna to the main antenna when operating in the diversity communications frequency band. A switch is carried by the portable handheld housing and connected to the RF circuitry and coupled between the diversity and main antennae and disconnects the diversity antenna when operating in the non-diversity band to prevent cross-coupling from the diversity antenna to the main antenna.

A mobile wireless communications device may include a portable housing, a printed circuit board (PCB) carried within the portable housing, wireless transceiver circuitry carried by the PCB within the portable housing, and an antenna carried by the PCB within the portable housing and connected to the wireless transceiver circuitry. The device may further include a first pair of electrically floating, electrically conductive, spaced apart, antenna beam shaping elements adjacent the antenna and spaced apart therefrom. A second pair of electrically floating, electrically conductive, spaced apart, antenna beam shaping elements may be adjacent the antenna and spaced apart therefrom. The first pair of antenna beam shaping elements may be positioned in an offset relationship relative to the second pair of antenna beam shaping elements.

A mobile wireless communications device may include a portable housing, a dielectric substrate carried by the portable housing having a front side facing toward a user and a back side opposite the front side, and a ground plane carried by the dielectric substrate. The device may further include at least one circuit carried by the dielectric substrate, and an antenna carried by the dielectric substrate adjacent an end thereof and electrically connected to the at least one circuit. A ground patch may be adjacent the front side of the dielectric substrate that is electrically connected to the ground plane and spaced apart from and at least partially overlapping the antenna.
摘要:
A low profile antenna has a meander length based on the full electrical wavelength of the signal being transmitted or received. The antenna can have either an open-loop structure or a closed-loop structure with a matching network. The low profile enables the antenna to be used in a card for a device such as a personal computer, personal digital assistant, wireless telephone and so on with minimal risk of the antenna breaking off, as compared with a prior art antenna having a higher height and thus more likelihood of being broken from its card.
