Patent ID: 6915111

Claim:
A system for testing a radio frequency (RF) device, the RF device having a body and an antenna, the antenna being configured to propagate an RF signal, said system comprising: a coupler configured to facilitate coupling between an RF signal and an RF device, said coupler comprising: a conducting member having a base wall, said base wall being configured to engage a portion of the body of the RF device; an antenna-receiving member configured to receive at least a portion of the antenna; and a tuning member configured to receive at least a portion of the antenna therein, said tuning member being aligned with said antenna-receiving member such that at least a first portion of the antenna is receivable by said antenna-receiving member and at least a second portion of the antenna is receivable by said tuning member; wherein resonance in a coupling coefficient of an RF signal injected into said coupler via said antenna-receiving member and said conducting member is tuned by said tuning member; and wherein the RF signal is injected in a first direction, and a coupled signal corresponding to the injected RF signal is characterized by a second direction, the first direction being substantially opposite to the second direction.
