The narrow bandwidth of microstrip antennas is one of the most important features that restrict its wide usage. This paper presents a new coplanar waveguide-fed compact rectangular microstrip antenna with the improvement of the bandwidth using the slot geometry and cutting rectangular periodic edges for the patch radiator. To develop this structure, we have conducted many optimization and investigation using Momentum Software integrated into ADS Advanced Design System and comparison of the results with CST Microwave Studio. The comparison between the simulation and measurement results permits to validate the final achieved antenna with an improvement of the bandwidth. This antenna has wide matching input impedance ranging from 1.7 to 3.5GHz with a return loss less than -10dB, corresponding to bandwidth 69.7% at 2.6GHz as a frequency center. The antenna achieved is a low cost, planar, and easy to be fabricated, thus promising for multiple applications in wireless communication systems. Details of the proposed antenna design and both simulated and experimental results are described and discussed.
