Dual-Port MIMO antenna design for IoT: Analysis and implementation

Abstract

The research presents a new type of antenna that makes use of MIMO technology, which employs multiple antennas for signal transmission and reception. This antenna also features a defective ground structure, a patterned ground plane that is frequently utilized to boost an antenna's performance. Adding or altering the ground plane patterns can enhance the antenna's performance. To improve antenna performance, a variety of designs, including rectangular and asymmetrical shapes, are being investigated, indicating a flexible method of antenna design optimization. The following features apply to the designed MIMO antenna: 60 x 60 mm2 in size, two ports are present. Operating Band: 1-6 GHz, Gain: 6.40 dBi, Return Loss (RL):-30.06 dB. The antenna is made to work in the 1-6 GHz frequency band, which includes a large variety of wireless communication frequencies. It specifically indicates appropriateness for WLAN frequencies such as 1.2 GHz, 2.4 GHz, 5.2 GHz, and 5.98 GHz that are used in IoT applications. A single radiating element with two slits and enhanced rectangular patches are features of the antenna's design. It can support sub-6 GHz WLAN bands as a result, making it appropriate for IoT applications that use these frequencies. In this research, a MIMO antenna with a DGS is shown. It has good performance characteristics, such as a broad operating band and applicability for IoT applications in different WLAN frequency bands. This antenna design might be useful for wireless communication systems needing multiport capabilities and increased performance.
