Abstract

In this work, two designs of a 16x1 array antenna with non-periodic AMCs structures are designed at a frequency of the 28 GHz. Four types of AMC pattern are designed and arranged to the upper and lower sides of the substrate surface. The AMCs are arranged unevenly by size and shape of the designs. Both designs of the antenna with AMCs are compared with the antenna without AMC. In comparison, between the proposed designs of 16x1 array antenna integrated with AMC and antenna without AMC, it shows that there is slightly enhancement of the antenna performance in terms of gain, bandwidth and side lobe level. The maximum of gain is 19.33 dB compared to the antenna without AMC of 18.61 dB. The bandwidth is increased up to 1 GHz, which meet the requirement at the frequency of 28 GHz The side lobe level is reduced from -16.7 dB to -19.1 dB and -16.7 dB to -20.3 dB for both designs antenna with AMCs when compared to the antenna without AMC. It can be seen that, the antenna integrated with AMC able to use at 5G technology without adding any layer and the thickness of the antenna.
