Abstract

A compact and broadband microstrip stacked patch antenna is presented. This antenna consists of two stacked patches fed with an S-shaped impedance matching network (IMN) connected by a probe. With this S-shaped IMN feed technique, good impedance matching and broadside radiation is obtained. Circular Polarization (CP) is obtained rotating the upper patch 90° sequentially with respect to the lower patch and truncating the corners. Additionally with four symmetric L-shaped narrow slots on patches, compact operation is obtained. The above antenna is of 56x56x11.8 mm³. The 3dB beamwidth of 77° is obtained. Also a peak gain of 7.12 dB is obtained. The voltage standing wave ratio (VSWR) is less than 2 for the impedance bandwidth of 20%. The radiation efficiency of antenna is 86.15%.
