A Compact Microstrip Patch Antenna for X-Band Applications
Keywords:Patch antenna, X-bands, HFSS, Resonant frequency
Nowadays, microstrip antennas are widely used in wireless applications. There are so many bands of frequency and they can be listed out L, S, X, Ka etc. For this work, it is only focused on X bands only. The range of frequency of X band is from 8 to 12 GHz. In this paper, the design and simulation of the compact microstrip patch antenna for X band applications are proposed and the main goal of this paper is to get good results from the designed antenna. The software used in this paper is HFSS 15 (High Frequency Structure Simulator 15). The proposed antenna is a rectangular microstrip patch with the dimensions of 6 mm x 5 mm and it is designed on the substrate material of FR4, with the dielectric constant of 4.4 and operating frequency of 11 GHz. After simulation, 2.8 dB gain is obtained and bandwidth equals to 700 MHz, directivity equals to 3.96 dB, VSWR (Voltage Standing Wave Ratio) equals to 1.24. These results show that antenna is very suitable for X bands applications such as satellite communication, wireless computer networks, etc.
