Abstract

Software for antenna design optimization have been widely used for various applications. In this paper, the utilization of numerical electromagnetic code based software in optimizing multiband VHF antennas for a transient radio telescope system is presented. Two antennas were simulated and the optimized designs were constructed and measured. These antennas can be operated at around 38 MHz, 73.5 MHz and 151 MHz, by combining V-shape half-wavelength dipole, traps and parasitic elements. Return losses down to of about -31 dB has been obtained, where the maximum gains were achieved at zenith direction for all operating frequencies. The proposed antennas are suitable to be used in a transient radio telescope which is operated in urban centres.
