Design of Four-Arm Equiangular Spiral Antenna in Mine Communication

Abstract:

According to the propagation characteristics of radio wave in mine tunnels, in order to realize the communication and detection in underground tunnels, a four-arm equiangular spiral antenna is presented in the paper, which based on the principle and structure of traditional two-arm spiral antenna, and reduces the antenna size. CST software is used to construct and simulate the antenna model. The antenna is tested by the PNA3621 vector network meter. Simulation and measurement results show that the antenna has good performance in 652MHz-3.012GHz frequency range, antenna input voltage standing-wave ratio VSWR and return loss RL are ideal, and antenna pattern is better, which agrees well with the simulated results.
