This paper presents a simple microstrip flltering-antenna with compact size for WLAN application. The T-shape resonator through an inset coupling structure can be treated as the admittance inverter and the equivalent circuit of the flltering-antenna is exactly the same as the bandpass fllter prototype. With a little extra circuit area, the proposed flltering-antenna has almost twice wider bandwidth, good skirt selectivity and high suppression in the stopband compared to the conventional microstrip antenna. |
