Design and Bandwidth Enhancement of Parasitic Patch Antenna and Comparison with U-Slot Microstrip Patch Antenna for GPS Applications

Abstract

Aim: The purpose of this research work is to design an innovative parasitic antenna for bandwidth enhancement and comparison with U-Slot microstrip patch antenna for GPS applications. Materials and Methods: The antenna was designed in the open source HFSS software. Two sample groups each of sample size ten were collected for both the antennas. Group 1 is taken as a proposed antenna innovative parasitic antenna and group 2 is taken as U - slot microstrip patch antenna. Both the antennas were designed at an operating frequency of 7 - 8 GHz. For bandwidth enhancement of an antenna, return loss was considered as a key factor in order to obtain the better bandwidth. Results: Antenna was designed in the HFSS software and after designing by giving far fields output graphs were displayed. The return loss obtained for innovative parasitic antennas was −31.3897 dB which have more bandwidth and return loss of 0.4682 dB for U - slot antenna which has very less bandwidth. The significance value obtained in SPSS was 0.0173 ($P < 0.05$) Conclusion: The innovative parasitic antenna provides more return loss and bandwidth at 8.1 GHz when compared to U-slot antenna for GPS applications.
