摘要

In this article, a quarter mode substrate integrated waveguide (QMSIW) self-octaplexing antenna array for fifth generation (5G) millimeter wave communications is presented. It consists of microstrip fed eight QMSIW antenna arrays to obtain the electromagnetic radiations at eight distinct frequency bands that lies in n257, n258, n259 and n260 of 5G spectrum for self-octaplexing operations. The designed self-octaplexing antenna array utilizes TE110 mode of the QMSIW resonator. The designed antenna array radiates at 25.8, 27.5, 29.5, 31, 35.6, 36.8, 38.2 and 39.7 GHz with the corresponding gains of 9.7, 10.7, 10.9, 11.0, 11.4, 11.7, 11.9 and 12.2 dBi, respectively. High inter-port isolations (> 33 dB) are obtained over all the operating bands of the self-multiplexing antenna array.
