Abstract
This letter offers metasurface-inspired multiple-input--multiple-output (MIMO) antenna with circular polarization (CP). The antenna radiating element consists of 1 × 2 array nonbianisotropic split ring resonator with an interdigital capacitance. Furthermore, a four-port MIMO antenna is designed with a 8 × 8 metasurface array (M-Array) on the ground plane. The dimensions of the proposed CP MIMO antenna are 4.6$\lambda _{0}$$\, \times\, \text{4.6}\lambda _{0}$$\,\times\, \text{0.128}\lambda _{0}$ at 28 GHz. The MIMO antenna with an M-Array offers a frequency range of 30.15% [(23.8 to 32.25) GHz], isolation above 55 dB and an overlapping 3 dB axial ratio bandwidth of 14% from 26.5 GHz to 30.5 GHz with a high gain of 18.5 dBi. The proposed MIMO antenna is simplified into an equivalent circuit model. Diversity metrics ensures good diversity performance including, envelope correlation coefficient (ECC $< $ 0.01), diversity gain (DG $\approx$ 10 dB), channel capacity loss (CCL $< $ 0.1 bits/Hz), and total active reflection coefficient (TARC $< $ –10 dB). The proposed MIMO antenna's operational range includes the mmWave band [(25 to 29.5) GHz]. It is well suited for 5G new radio smart devices due to its better performance and compatibility with 5G communication standards.
期刊介绍:
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
