Abstract

Wireless technology, a longstanding focus for researchers, has evolved into an exciting telecommunications topic over several decades. The most recent iteration, Fifth Generation (5G), has been introduced at high frequencies, commonly called millimeter waves. An integral component supporting wireless communication is the antenna. This report details the design of a microstrip antenna operating at a frequency of 26 GHz. The antenna is configured as a rectangular patch microstrip, utilizing coupled slot feeding, organized as an array, and implementing a ring as the gain enhancement technique. The designed antenna undergoes observation for both single-element and 1x2 arrays, both with and without rings. A thorough analysis encompasses gain, bandwidth, return loss, and radiation pattern. The antenna design, developed at a frequency of 26 GHz, demonstrates a substantial gain increase of up to 10 dB and 14 dB in the single-element and 1×2 array configurations achieved by adding a ring. The designed antenna surpasses the previous works' gain of about 3 dB more.
