This paper discusses the design, fabrication, and measurement of a two-layer, 2×10 elliptic, microstrip series fed antenna array operating at 28 GHz for 5G and mm-wave user equipment. A branch line coupler was used as a feeding network that can generate three beams. The peak gain value of each beam was 13 dBi at 28 GHz. The gain value was above 10 dBi within a beam coverage of −45° to 45°, and the peak gain value for the 26.5 GHz to 29.5 GHz band was above 10 dBi. The impedance bandwidth of the proposed design was below −10 dB in the 26.5 GHz to 29.5 GHz band. The dimensions of the 2×10 antenna array with coupler were 80×40×0.203 mm 3 on Rogers RO4003 substrate. This design is suitable for 5G mobile user applications due to its low cost and compactness.
