Abstract
This paper presents an active integrated antenna using a T-shaped microstrip-line-fed slot antenna which acts as DC isolation in the RF path and has a wide bandwidth. A fabricated parallel feedback antenna oscillator has a stable oscillation and a clean spectrum at the frequency of 10.05 GHz, which is only 0.5 % deviation from the designed frequency of 10 GHz. The measured EIRP is 37.79 mW, and the cross-polarization levels are at least -15 dB lower than the co-polarization ones for all directions.
