Abstract

This paper is a study on the electromagnetic band gap (EBG) and artificial magnetic conductor (AMC) on the radial line slot array (RLSA) antenna structure at a frequency of 28 GHz. The RLSA antenna is known based on its characteristic which has high gain, durable, simple structures, high efficiency and low cost of fabricating. This project is focusing on the study of the RLSA antenna with the Electromagnetic Band Gap (EBG) and Artificial Magnetic Conductor (AMC) with analyzes the effect of number EBG and AMC structures applied to the antenna. It enhances the performances of the RLSA antenna before the EBG structure is added. This may be due to eliminating the several numbers of slots on the radiating plate is the reason for the present number of EBG structures applied to it. The lowest value of S11 for eight (8) units EBG is -41.4686 dB at a frequency of 29.86 GHz, the directivity value is 25.60 dBi and realizes a gain of 25.26 dB at a frequency of 28 GHz. While the AMC structure can reduce the side lobes from -2.7 dB for nonelement of AMC to -1.7 dB for eight (8) and nine (9) elements. This RLSA antenna with AMC and EBG produces high directivity which is 26.10 dBi compared to conventional RLSA antenna which is 21.70 dBi. This antenna can also be used as widely applications such as RADAR and satellite communication.
