Summary: This article presents a compact multiple-input-multiple-output (MIMO) microstrip antenna system that covers the 2.4 and 5 GHz wireless local area network (WLAN) bands. The dual-band characteristics are achieved by exciting the TM01 and TM03 modes of a microstrip antenna, using a rectangular slot to improve the radiation capability of the TM03 mode, and utilizing two probes to tune the resonant frequency of the TM01 mode. High interport isolation at the two WLAN bands is achieved through isolation enhancement at the lower and upper-frequency bands, introducing split loops to reduce mutual coupling at the 2.4 GHz band, and adding dipole elements in the rectangular slot for high isolation at the 5 GHz band. The proposed antenna system operates at 2.25-2.63 and at 5.14-6.06 GHz, with measured maximum mutual coupling of less than -15.3 dB at both operating frequency bands.

Summary: This letter introduces a dual-wideband dual-polarized magnetoelectric dipole antenna that operates at the prominent frequency bands of 1.7-2.7 GHz and 3.3-5.0 GHz in Sub-6 GHz. The antenna design includes a cross ME dipole for dual-polarized radiation and a cross strip with a notched band. Additional features like a cross patch and a metal baffle improve impedance matching and stability. The measured results demonstrate the antenna's dual-wideband and dual-polarized characteristics, making it suitable for base-station applications in Sub-6 GHz.

Summary: This study proposes a portable L-shaped microstrip patch antenna with enhanced gain for IoT 2.4 GHz ISM applications. Through parametric simulations, it is found that the antenna's matching impedance and performance can be improved by modifying the rectangular back slot and fine-tuning the front L-shaped patch. The finalized antenna operates at 2.4 GHz with a 98% radiation efficiency and peak gains of 2.09 dBi (measured) and 1.95 dBi (simulated).
