Abstract

A new concept, design and realization of active slot antennas as simple integrated uniplanar parts of transmitter-receivers is presented in this paper. All circuits are realized in coplanar waveguide techniques (CPW). The common oscillator with one low-cost FET (NE76084) works like a transmitter and local oscillator for the receiver and has electrically controlled frequency. The model is realized at a transmitting frequency of 5.25 GHz. Transmitter radiating power is about 22 dBm and mixer isotropic conversion gain is 2.7 dB. The concept and design can be applied to microwave as well as to millimeter-wave frequencies.
