Design and Comparison of a Rectangular-Slot-Loaded and C-Slot- Loaded Microstrip Patch Antenna

The aim of this paper is to design and compare microstrip antennas fed by coaxial probe. A coaxial feed, rectangular-slot loaded, microstrip antenna is proposed for linear polarization and compared to the C-slot-loaded microstrip antenna. The compactness of the antenna is easily obtained by inserting a Cslot. The rectangular-slot-loaded microstrip antenna and C-slotloaded microstrip antenna is comparing their simulated value using IE3D.
