Abstract
We propose square shape patch antenna in this research work. Focus of the work is to obtain large bandwidth with compact ground plane for wireless applications. The proposed antenna is designed using dielectric material of FR4 having height of 1.6 mm and having r of 4.4. We simulated the proposed antenna in CST Microwave Studio. Simulation results show that the proposed antenna achieved bandwidth from 2.33 GHz to 12.4 GHz with radiation efficiency more than 90% in ultrawideband range. The proposed antenna covers the range of ultra wideband from 3.1 GHz to 10.6 GHz, the range of local area network, wide area network, and also covers the range of satellite communications (for both uplink and downlink).

Summary
Antenna is one of the basic building blocks of wireless applications. Antenna plays an important role in telecommunication industry and is used to transmit and collect electromagnetic (EM) waves. For the reason of those inventions, scientists need such an antenna which is light in weight, cheap in cost, having good performance, portable, and easy to fabricate. Microstrip patch antennas are mostly used in mobiles phones and laptops, etc. Patch antennas are cheap in cost, having low profile, and easy to fabricate. Patch antennas have three parts−patch, substrate, and ground. In early 1970, Howell and Munson were able to design a practical antenna. Patch antennas have some limitations as well such as its bandwidth is very small and gain is not good. The proposed antenna is square in shape, which operates in the range of 2.33 GHz to 12.4 GHz; accomplishing the UWB bandwidth improvement. Rest of the paper is organized as follows: Section II discusses problem statement, literature review, and outlines contributions of the work, Section III explains basic structure of the proposed antenna design, while Section IV shows its simulation results from CST Microwave Studio
