Mutual Coupling Reduction among Closely Spaced Linear Array Reconfugrable Microstrip Antenna
Abstract
The fifith-generation 5G multiple-input multiple-output (MIMO) microstrip antenna with isolation enhancement that is tiny and based on a bandpass metamaterial (BPM) is presented in this paper. The expectation of higher data rates drove the development of 5G mobile communication networks. The performance of a two-element microstrip antenna array with and without bandpass metamaterial, as a mutual coupling reduction tool, is introduced. The antenna consists of two parts, with its radiators positioned to report the opposite direction. The array antenna's overall dimensions are small, measuring 40 × 72 × 1.6 mm³. The proposed isolated two-element antenna array produces bandwidth and mutual coupling are 16GHz at -53.83dB, respectively, while the rectangular microstrip patch antenna array produces these values at 12.03GHz at -14.69dB. When compared to the double microstrip parallel antenna, the double microstrip opposite antenna with BPM is superior in terms of mutual coupling. The increasing demand for faster data speeds in the rapidly changing field of mobile communication technologies is met by the presented creative antenna.
