Abstract:

Nowadays, microstrip patch antenna becomes popular in wireless communications due to their low-profile structure, Lightweight& low volume, low fabrication cost. So that they are extremely compatible with embedded antennas in handheld wireless devices. In this project, the rectangular microstrip patch antenna is designed for an operating frequency of 1.9 GHz, and the substrate used is FR4 epoxy having a low dielectric constant of 4.4, the dielectric loss tangent of 0.02, and the substrate thickness is 1.6mm. This design is simulated by HFSS and used to obtain the most suitable configuration in terms of desired values of Return Loss (RL), Voltage Standing Wave Ratio (VSWR), and bandwidth by using 4.4 dielectrics constant and varying the length inset feed. We get the RL is –15.4142dB, VSWR is 1.4083; this indicates there are no losses, the gain is 1.3069dB, the directivity is 1.4087dB, and the BW is 78.5MHZ by using the inset feed line of 9.8291mm. When the inset feed line decreases to 9.1062mm, the RL becomes -12.7351 dB, VSWR is 1.600, and the BW is 50.6MHZ. Therefore, the BW is enhanced from 50.6MHZ to 78.5MHZ.
