Abstract :
In this letter, a miniaturized microstrip patch antenna with enhanced bandwidth is presented. Based on the transversal signal-interference concept, the dual feedline structure is employed to reduce the nonradiating side of the antenna element. In order to extend the impedance bandwidth, an additional T-shaped stub resonator is introduced. Compared to a typical rectangular patch antenna, 32% size reduction and 17.0% impedance bandwidth (S11<;-10 dB) enhancement are achieved, respectively. Good agreement between simulation and measurement can be observed.
