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.
