Design and Comparison of Two X Slotted and One Wide Slot Loaded and No Slot- Loaded Square Shaped Micro-strip Patch Antenna

Abstract: In this paper we present a proposed design for square shaped micro-strip patch antenna by cutting two X shape slots and one wide slot at the surface of the square patch. Using proposed antenna design and probe feeding at proper position we will compare the resultant return loss, VSWR and impedance with the results of no slot loaded square shaped micro-strip patch antenna. We are using IE3D simulation software for designing and analysis. We have observed that using slotted patch antenna and using probe feed at proper location we can get better return loss, VSWR and impedance.

Keywords: Slotted Square shaped micro-strip patch antenna, return loss, VSWR.
