Progress In Electromagnetics Research C, Vol. 162, 70-80, 2025
Abstract
A novel compact four-element MIMO antenna system is developed, featuring a rectangular Microstrip patch structure integrated with dual vertical grooves. The projected antenna design incorporate slits, triangular slot, and DGS to realize dual-band resonance with simultaneously multiband response and mitigating mutual coupling effects. The antenna operates effectively at 0.9 GHz and 2.4-2.6 GHz bands, supporting multiple IoT and wireless communication standards such as GSM (0.9 GHz), Lora (2.4 to 2.5 GHz), Wi-Fi (2.4 GHz), Bluetooth (2.4 GHz), LTE (Band 8 , Band 7, Band 41 and Band 53), and 5G (n8, n41). The antenna demonstrates satisfactory impedance matching, achieving return losses of -16.16 dB at 0.94 GHz and -31.19 dB at 2.496 GHz, with isolation levels exceeding -15 dB. The antenna delivers stable far-field radiation with 2.8-3.6 dBi gain, and prototype validation demonstrates strong agreement with simulations, confirming its suitability for compact, high-performance IoT (2.4 GHz) and 5G Sub-6 GHz devices.
