Performance Optimization and Comparison Analysis of Different Conventional Array Antennas at UHF Band

Due to increase need for higher communication capacity in wireless and mobile communication system, high gain, directional and omnidirectional antennas have become more attractive for wireless communication applications. This paper presents the results of the performance optimization and comparison analysis of three different conventional antennas namely log periodic dipole array LDPA , folded dipole array FDA , and star array SA antennas designed and fabricated at the ultrahigh frequency UHF band of 900MHz to 1880MHz. Some antenna characteristics such as half power beam width HPBW , directivity, gain, and efficiency were used as performance metrics. The results show that each of the three conventional array antennas shows good performance and unique characteristics. The SA antenna has the best performance with an optimized gain of 9.2 dB compared to the designed gain of 8.0 dB, which suggests that it is best of the three antennas for high gain and omnidirectional antenna applications.
