Abstract

The advancement of the latest WiFi standard has spurred the development of a novel antenna design. A novel antenna design with broadband, low side-lobe, and high-gain omnidirectional radiation is proposed in this paper to achieve high-speed WiFi signal transmission. This design involves an innovative modification of the ground plane in a rectangular microstrip patch antenna, effectively achieving ultra-wideband, low side-lobe, and omnidirectional radiation characteristics. A 1 × 4 series-fed array, composed of antenna units with these attributes, is utilized to attain the antenna's high-gain feature. Simulation results using CST Microwave Studio® demonstrate that the designed antenna array can achieve a reflection coefficient of less than -10 dB in the range of 3.5 GHz to 10.4 GHz, and the side-lobe levels are consistently below -10 dB in the range of 3.8 GHz to 6.2 GHz, with gains exceeding 6 dBi. The electric field distribution analysis of the patch units substantiates the antenna's omnidirectional radiation capability. The designed antenna possesses advantages such as compact size, light weight, and ease of implementation, making it suitable for WiFi 7 applications and other similar areas.
