Design and Simulation of V-Type Dipole Antenna

摘要

The VHF low band (30MHz-100MHz) is a very important spectrum in radio astronomy. In this band Galactic noise is often quite strong. This thesis introduces the design and simulation of a blade-type vibrator antenna. Antenna operating in 30MHz-70MHz can satisfy the requirement of low-frequency radio observation. A blade-type vibrator antenna based on HFSS simulation software is introduced. The VSWR (voltage standing wave ratio) of antenna satisfies the galaxy noise-limit condition in the working frequency band, and the antenna has the characteristics of simplicity, low cost and easy production. It's a attractive candidate for large low-frequency radio telescope arrays.
