Abstract

In this paper, a novel reconfigurable angular cone antenna that employs a rotatable fan ground plane for reconfiguration is introduced. By regulating the number and orientation of external grounds, the radiation range is progressively broadened, enabling the antenna to exhibit diverse radiation modes. Experimental results demonstrate that the antenna can successfully switch between three modes and validate seven distinct beam directions. These beam directions include: (1) a single ground plane at 45°, 135°, 225°, and 315°; (2) two ground planes at ±45°; and (3) four ground planes creating an omnidirectional radiation pattern. Notably, the antenna boasts a broad bandwidth of 60.66% (covering 1.2-4.9 GHz; VSWR < 2.0) which cover 2G/3G/4G/5G communication bands, while maintaining an antenna efficiency exceeding 90%, marking a significant performance enhancement.
