Investigation on the performance of U-Slot and Truncated Corner Patch microstrip antenna
Abstract
In this study, the performance of a U-Slot (U-S) microstrip patch antenna and a Truncated Corner Patch (TCP) microstrip patch antenna was investigated at a frequency of 10GHz, utilizing Roggers 5880 as the substrate material. The simulation results indicated that U-S and TCP have: impedance of 284Ω and 50Ω, return loss 2.5 dB and 11dB, reflection coefficient of -7dB and 0.3 dB and Voltage Standing Wave Ratio (VSWR) of 9 dB and 3 dB. Based on these results, it can be observed that that TCP microstrip patch antenna outperform the U-S microstrip patch antenna in term of impedance, return loss and reflection coefficient. The TCP antenna exhibits a lower impedance of 50Ω compared to 284Ω for U-S antenna. Additionally, the TCP demonstrates a higher return loss of 11dB and a lower reflection coefficient of 0.3 dB indicating better matching and reduced signal reflection compared to the U-S antenna.
