12, p . 1701-1705, December 1988). The planar oscillator using a periodic leaky wave antenna can be used as a transceiver. This can be attained by slight modifications of the single and coupled oscillators described above . In such cases, the FETs perform a dual function, serving as the source for the transmitted signal and as self-oscillating mixers for down conversion of the received signal [27] . Much more compact integrated receivers than those in [27] were designed and tested by an ingeneous use of a coupled slot antenna [28, 29].

The circuit structures of different types of active integrated antennas are discussed. Various circuits integrating solid state devices and low-profile passive antenna elements are demonstrated.
