1 x 3 Rectangular Split Ring Resonator Antenna Array with DGS for mmWave Communication

Radiating patches and ground plane are etched by a rectangular slot to improve the radiation characteristic. High gain and radiation efficiency for mm-wave communication are proposed in this paper. Low-profile antenna arrays are obtained by Rectangular Split Ring Resonator (RSRR) with Capacitance Strips Loaded (CSL). Defected ground structure (DGS) and ‘L’ shaped stubs on the parasitic patch are used to move the resonating frequency of 28GHz to 26GHz. The optimal radiation characteristic of the proposed antenna array is obtained by numerical analysis using commercially available EM simulation software (HFSS). The proposed antenna has overall dimensions of 32 x25x0.8mm
³
and is printed on a FR4 substrate with a height of 0. 8mm. Radiating features of the mmwave antenna array are confirmed successfully in 23. 5GHz-26.5GHz. The maximum gain of 8dB and above 94% of radiation efficiency is achieved in this article. Due to its attractive profile, compact configuration, high gain, high radiation efficiency, and better impedance bandwidth, the suggested antenna array will work for millimeter-wave applications, mobile communications, and radar applications.
