ACTIVE INTEGRATED ANTENNA USING A T-SHAPED MICROSTRIP COUPLED-PATCH ANTENNA

摘要

In this paper, an active integrated antenna using a T-shaped microstrip coupled patch antenna, which acts as DC isolation in the RF path, is proposed. The designed feedback-antenna oscillator has stable oscillation and a clear spectrum at the frequency of 5.813 GHz, which is only a 0.2% deviation from the design frequency. The measured EIRP is 19.2 mW, and the cross-polarization levels are at least -13 dB lower than the co-polarization ones for all directions.
