초록

A horn antenna with corrugation structure and a PTFE(Polytetrafluoroethylene) teflon(relative permittivity=2.1) dielectric lens for good impedance matching characteristic and high gain performance is proposed in this paper. The proposed antenna shows measured return loss below —25 dB over the operating X band(8～12 GHz), the peak gain of 22.3 dBi at the center frequency(10 GHz) and has overall size of 110 mm×110 mm×135 mm. Considering the performance of the proposed antenna, it is suitable for being inserted in a radar level transmitters, particularly for gas tanks on vessels or off-shore plants containing gas with very low reflectivity and relative permittivity such as LNG or LPG.
