Abstract

Radio astronomical instrumentation has become a fascinating field of research in astronomy. In this paper, a design of multiband novel antenna for low-frequency radio telescope is proposed. The multiband has been achieved by combining V-shape half-wavelength dipole, traps and parasitic elements. The low return loss, multiband and maximum gain within the zenith direction is provided by V-shape half-wavelength dipole, traps and parasitic elements respectively. The study showed return loss of about -20 dB, -17 dB and -13.6 dB for three different frequencies with maximum achievable gain of about 10.28 dBi. Measurement result shows that the proposed antenna can work properly and meet well to be used in a transient radio telescope which is operated in the urban centers.
