Abstract
A varactor-tuned active integrated antenna which is consisted of a series feedback voltage-controlled oscillator (VCO) and a matched slot antenna is proposed. The fabricated antenna has a stable oscillation at 5.8 GHz band, and the frequency varies form 5.73 GHz to 5.97 GHz, with less than 1.28 dB of amplitude deviation over the frequency range.
