This paper presents a four‐port design for multiple‐input and multiple‐output (MIMO) dual‐loop antennas in 5G C‐band access point applications. The dimensions of the design are 90 mm × 90 mm × 15 mm. It consists of four dual‐loop antennas, four feed lines, and a reflector. The design uses a phase difference of 90° among the antennas to improve the isolation. It was observed that a dual‐loop antenna with another nearby dual‐loop antenna generates two modes to form the bandwidths WRC 5G C‐band (3.4‐3.6 GHz) and China 5G C‐band (3.3‐3.8 GHz). A rectangular parasitic element placed in the middle of the four dual‐loop antennas enhances the antenna gain. The proposed design has a compact size, good gain, low cost, and easy manufacturing, and is a suitable candidate for practical applications.
