Improvements in and relating to antennae for a portable telephone equipment
Abstract
An antenna system for portable electronic apparatus, particularly for the handset of a cordless telephone system, and comprising two antenna, a first (shown) mounted on a flap (2) and comprising a groundplane 5 and active monopole 4 fed by a coaxial feed 6 from electronic circuitry (not shown) in the main section of the handset 1. The flap is pivotally connected to the main section of the housing 1, and is folded down against the main section when not in use. Another similar antenna is fitted in the main section, and both antennae are connected to the transceiver circuitry via the same node. The two antennae are specially designed so as to introduce deliberate mismatch so as to provide an effective switching system between the two antenna without the need for separate circuit elements.
