Abstract :
A new suspended plate antenna is presented for the enhancement of impedance bandwidth. The probe-fed plate antenna is suspended above a ground plane and its center portion is concaved to form a "V" shape. The experiment and simulation show that without increase in size the proposed antenna is capable of providing an impedance bandwidth of up to 60% for |S11|<-10 dB with an acceptable gain of 8 dBi.
