A 2x2 Millimeter-Wave Microstrip Antenna Array for 5G Applications

Abstract

In this paper, microstrip antenna array is designed and simulated for 5G applications. The array was designed with the intent to cover the millimeter-wave spectrum at 27GHz frequency. The substrate used in this antenna construction is Rogers RT Duroid 6002 with a loss tangent of 0.0012 and dielectric constant 2.94. The idea behind this research is to design antenna array for 5G systems able to operate in the frequency band of 24.25 – 27.5 GHz. Initially, a conventional antenna is designed. Thereby 2X1 microstrip antenna is designed and finally, a 2X2 antenna array is designed. In each stage, the antenna parameters such as S11 parameter, gain, and VSWR are calculated. Comparisons are also drawn concerning the directivity of the three antenna configurations discussed. For the end design which involves a 2X2 microstrip antenna array, the S11 is calculated to be -31.94 dB at the frequency of 26.78 GHz. The gain achieved was 11.02 dB and the directivity is found to be 11.12 dB. All the important findings from the simulations performed are tabulated.

Design and simulation of a novel miniaturized printed antenna with ultra-wideband and high gain for millimeter-wave wireless applications

“…However, mm-wave communication suffers from several propagation constraints, including high path loss and rain. Research on mm-wave antenna design in many applications such as 5G wireless communication [7], sensing, and security has become of interest. Many researchers worldwide have launched a series of studies about mm-wave micro-strip antennas [8,9], but the disadvantages of weak gain and efficiency remain constraints.…”

“…The work of [21] proposes an antenna with DGS on the ground plane to compact the size of the microstrip antenna without the degradation in performance. This antenna is realized using an array consisting of 2 × 2 mm-wave microstrip antenna array usable in 5G applications in [22]. The work in [23] proposed a single band antenna design for future millimeter-wave wireless communication at 38 GHz.…”
