Design and research of an improved regular hexagonal planar UWB antenna

Abstract

An improved planar UWB antenna based on hexagonal structure is designed. By introducing the defect structure to the ground plane of the regular hexagonal antenna, the -10dB impedance bandwidth of the antenna is 3.0-19.2GHz, covering the frequency range of UWB communication and higher frequency range. The antenna has a simple structure and a size of 26mm*31mm*1.6mm. The pattern and impedance matching in the whole bandwidth range meet the requirements of UWB communication.
