Abstract—Rectangular microstrip patch antennas, although having many advantages, usually suffer from having narrow bandwidth. Changing the feed point, or adding slots to the patch or to the ground plane or the addition of resonant circuits to the structure are different methods that can be applied for enhancing the bandwidth. Slots are usually added for creating multiple band operations. In this work, design and implementation of a rectangular microstrip patch antenna with double L-Shaped slots is proposed for enhanced bandwidth. Design is done with simulation verification of the problem and testing of two prototype circuits. Simulated and measured responses for both of the antenna circuits are demonstrated. One circuit indicated about 600MHz bandwidth at 2.6GHz center frequency and the other one about 1GHz bandwith with center frequency being around 2.4GHz.
