Abstract

A feed system that has been presented consists of high-gain antenna arrays that each have six slots and are arranged on a single substrate layer. This system makes use of a phase shifter that is not frequencydependent and a power splitter that is constructed on the design of a binary T-junction power splitter. The frequency of the signal is not taken into consideration by the phase shifter. In order for the antenna to attain its front-to-back ratio and high realized gain in ultrawideband areas, the feeding mechanism of the antenna is designed to be out-of-phase. This is done in conjunction with the correct antenna array architecture, which is implemented on distinct rows (2.5–6.8 GHz). Because of this, the antenna is able to accomplish both a high gain and a high front-to-back ratio (7.5–9.5 GHz). Applications that require communication over a wide band are appropriate candidates for the antenna that has been presented because of its vast bandwidth, high gain, and outstanding directivity. These characteristics make it an ideal contender for these applications. These are all limitations of earlier designs that have been reported in the literature, and they are all eliminated by the feeding system. The feeding system contributes substantially to an improvement in the array radiation directivity.
