ABSTRACT:
A single-turn loop antenna suitable for inclusion within the cabinet of a television receiver has at least one gap forming a pair of feed terminals. Circuitry connects to the feed terminals for tuning the antenna over at least a portion of the television frequency bands and for coupling signals from the feed terminals to a transmission line. The circuitry provides isolation so the tuning of the antenna by the tuning circuitry is unaffected by the impedance of the transmission line or its terminating impedance and variations thereof. The circuitry is affixed to the loop proximate to the feed terminals, and the transmission line is affixed to the periphery of the loop and departs therefrom at a neutral point located, for example, opposite to the gap.
