Chinese Character-Shaped Artistic Patch Antenna

Abstract

This contribution presents a novel design of a circularly polarized (CP) array antenna composed of the Chinese character-shaped artistic patches: Zhong and Guo. Namely, the CP Zhong-shaped patch and the Guo-shaped patch join together via a feeding network to form a two-element antenna array. This is the Chinese country name of China printed in the boldfaced SimHei font. Attributed to its artistic nature, this is the first design that breaks the design principles of CP antenna array, wherein, first, nonidentical radiating elements are used, and second, nonrotated elements are excited with quadrature phases. The experimental results in combination with simulations validate that the Zhong-Guo artistic antenna exhibits a unidirectional gain of 8.2 dBic with an operating bandwidth of 0.72 GHz. The achieved bandwidth sufficiently covers the 14 channels of IEEE 802.11 at 2.4 GHz wireless local area network band.
