A novel wide beamwidth microstrip patch antenna fed by a 1 : 5 unequal Wilkinson power divider with a low profile of 0.027λ 0 is presented. A circular patch and an independent feeding concentric metal ring can realize the broad half-power beamwidth (HPBW) in the far field. A 1 : 5 unequal Wilkinson power divider is designed as the antenna feed. The HPBWs of the antenna reach 258 • and 267 • in XZ-plane and Y Z-plane, respectively, covering the whole upper half space at central frequency (2.54 GHz). The results of simulation and measurement show great consistency.

A novel single-layer coplanar-fed circularly polarized (CP) microstrip antenna is proposed in this article. In order to improve the CP performance, a new sequential rotating feed network based on 3/4 λ (where λ is the wavelength in the medium) phase shift line is adopted in the antenna design, which is on the same plane as the radiating patch to achieve low-profile characteristics. A curved microstrip resonant structure is loaded around the radiating patch, the half-power beam width (HPBW) of the antenna is obviously widened. Meanwhile the height is only 0.06 λ 0 , thus low profile and wide-beam characteristics are achieved. In order to prove the effectiveness of the design method, a prototype is fabricated and measured. The measurement results show that it has good impedance matching (from 24.7 to 27.6 GHz) in the 5G mmWave bands. Within the operating bandwidth of the antenna, the HPBW of antenna can reach 125 in xoz-plane and 110 in yozplane. This design method can suitable for 5G mobile communication systems in future.
