Abstract
Development of antenna for a radio telescope system has become a fascinating research area in the field of radio astronomy. In this paper, a design of compact multiband VHF antenna for a transient radio telescope system is proposed. The multiband has been achieved by combining V-shape half-wavelength dipole, traps and parasitic elements. Return losses of about −12.45 dB, −25.15 dB and −29.42 dB are obtained at three different frequencies, where the maximum gains are achieved at zenith direction for all operating frequencies. The proposed antenna is suitable to be used in a transient radio telescope which is operated in urban centers.
