초록 ▼

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.

대표청구항 ▼

A portable electronic apparatus having a housing made, at least in part, of insulating material, and incorporating an antenna comprising an active element and a ground plane, said active element comprising a length of conductive material disposed parallel to the ground plane and fed from one end; wherein the antenna is mounted on a sheet of insulating material forming part of said housing, and comprises a first rectangular sheet of conductive material forming said ground plane, and a second, elongate, rectangular sheet of conductive material forming said active element; and wherein the housing is in two sections which are movable with respect to one another, and wherein said sheet of insulating material forms part of one of said sections, and wherein the other section contains electronic circuitry which is electrically connected to said antenna; and wherein said other section includes a second antenna which is likewise electrically connected to said electronic circuitry; and wherein both antennae are connected to said electronic circuitry via the same node; and wherein said antennae are electrically mismatched as seen by the electronic circuitry; and wherein a mechanical tuning element is attached for movement with one of said sections of the housing, said tuning element being positioned such that as the two sections are moved with respect to one another, the element detunes one of the antennae, but not the other, thus introducing an electrical mismatch between them.
