Elongate personal communications apparatus

Elongate personal communications apparatus

A personal communications apparatus comprises an elongate body 202 incorporating an antenna diversity arrangement in which first and second antennas ( 102 A, 102 B) are located at opposite ends of the body. In one embodiment a microphone ( 114 ) is located at the tip of one antenna ( 102 A) and a lo...

description A personal communications apparatus comprises an elongate body 202 incorporating an antenna diversity arrangement in which first and second antennas ( 102 A, 102 B) are located at opposite ends of the body. In one embodiment a microphone ( 114 ) is located at the tip of one antenna ( 102 A) and a loudspeaker ( 116 ) at the tip of the other antenna ( 102 B). The microphone ( 114 ) and loudspeaker ( 116 ) act as top loads to their respective antennas, thereby enabling the use of shorter antennas. The antennas ( 102 A, 102 B) may be formed from coaxial cable, enabling them to provide electrical connections between the microphone ( 114 ) or loudspeaker ( 116 ) and transceiver circuitry in the body of the apparatus. By arranging for the microphone ( 114 ) and loudspeaker ( 116 ) to have low impedances at radio frequencies, the coaxial cable acts as an inductive stub and enables the antennas ( 102 A, 102 B) to be further shortened.
