Abstract
Aperture-coupled microstrip line feed circularly polarized patch antenna is designed and its performance characteristics are observed by changing its feed orientations. The perfect impedance matching and appreciable axial ratio bandwidths are achieved from the current model. The complete analysis is done by changing feed line orientations and by placing special slots on the ground element. The antenna compactness can be achieved by placing shorting pin at appropriate location on the axis of feed line. Antenna output parameters are computed with finite element method based simulation. A microstrip line patch antenna is designed which is a circular microstrip line coupling through four Γ-shaped slots to generate four sequentially phased sources to excite the single layer patch antenna.
