In this letter, a new method is proposed to achieve high port isolation and wideband harmonic suppression for two closely placed asymmetric antennas by using integrated filtering structures cascaded on the feeding microstrip lines. The proposed asymmetric antenna pair operates normally at 2.34 to 2.6 GHz and 3.31 to 3.69 GHz, respectively, containing the WLAN band (2.4‐2.484 GHz) and the fifth generation (5G) bands of China Telecom (3.4‐3.5 GHz) and China Unicom (3.5‐3.6 GHz). Compared to the reference antenna pair, the proposed antenna pair has an enhancement in isolation of 40.8 and 38.1 dB at 2.45 and 3.5 GHz individually, and the higher harmonics of up to 18 GHz generated by the reference antenna pair can be suppressed. The gain of the proposed antenna pair decreases by an average of 8.8 dB in the higher harmonic frequency bands. The measured results of the manufactured antenna pair agree well with the simulated results, indicating that the designed antenna pair has good dual‐band decoupling and wideband harmonic suppression characteristics. This method particularly reduces the complexity of the decoupling antenna design and is suitable for the future multi‐functional terminals.
