  • Abstract
    The dipole-based antenna has been employed in many radio telescope systems. By utilizing this type of antenna, the possibility to conduct all sky monitoring and high spatial resolution observation in the same time can be provided. In this research, a new dipole-based antenna system will be developed for 21cm line observation. The dipole-based antenna is optimized in terms of standing wave ratio (SWR), gain and beamwidth. Initial results show a good achievement on SWR level, down to 1.005.
