V-shape wire-structured HF bowtie antenna

This paper presents the investigation on a horizontally polarized HF antenna. The antenna is aimed to have small size, wideband, and high power gain. V-shape wire-structured bowtie antenna has acceptable performance in both aspects of gain and VSWR. Detailed analysis of this V-shape wire-structured bowtie antenna is carried out using Numerical Electromagnetic Code (NEC-2). The simulated results serve to verify the performance of this antenna and to optimize various antenna parameters such as the number of wires, the open angle of two arms and feed gap width. The measured and simulated results show that the VSWR of this antenna is within 2.5:1 over 6~30 MHz and the average power gain is about 13 dBi.
