Abstract :
A small quarter-wave rectangular microstrip patch antenna with the impedance bandwidth of 35% was constructed for the frequency of about 2 GHz. The antenna has a probe feed with an integrated capacitor to compensate for the probe inductance and produce a dual-resonant structure. The radiation pattern of the proposed antenna is fairly omnidirectional and the polarization separation is low, so it is suitable for certain applications in mobile communications.
