摘要

目的:本研究的目的是设计一种创新的寄生天线，用于GPS应用的带宽增强，并与u槽微带贴片天线进行比较。材料与方法:采用开源的HFSS软件进行天线设计。两种天线分别收集了两组样本，每组的样本量为10。将第1组作为天线创新寄生天线，将第2组作为U槽微带贴片天线。两种天线的工作频率都在7 - 8ghz。在天线的带宽增强中，为了获得更好的带宽，回波损耗是一个关键因素。结果:在HFSS软件中设计天线，设计完成后给出远场输出图形。新型寄生天线的回波损耗为−31.3897 dB，带宽更大;U槽天线的回波损耗为0.4682 dB，带宽更小。结论:在GPS应用中，与u槽天线相比，新型寄生天线具有更高的8.1 GHz回波损耗和带宽。

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

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.
