Investigation on OMYA with single superstrate layer

Abstrak

The need for wireless communication technology is increasing rapidly. Many people are already using internet data services offered by providers or using wireless fidelity (Wi-Fi) services. One of the things that must be considered in Wi-Fi technology is that it requires antenna characteristics that have a relatively small shape and light mass. This paper aimed to improve gain and to analyze the performance of octagon microstrip Yagi antenna (OMYA) with a single superstrate layer. The antenna was designed, simulated, and measured. The experimental result presents that this concept is capable to produce a gain of 11.80 dB, a return loss of -23.24 dB, and the bandwidth is up to 800 MHz with total dimensions of 70×75 mm.
