Abstract

This paper reports the optimization of a center slotted active patch antenna. The antenna was optimized theoretically using an FDTD analysis of its near field standing wave pattern; and experimentally using its bias voltage, injection voltage, and component values to achieve a harmonic level of -20 dBc, SSB phase noise level of -99 dBc/Hz at 10 kHz, sensitivity of -97 dBm and a gain of 4.5 dB. The transceiver has low component count with only two BJTs and one FET and is therefore well suited for low cost and low power application.
