CRLH Leaky-wave beam-forming antenna with enhanced gain for the V2X communication

Abstract

In this paper, a CRLH Leaky-wave twodimensional array antenna for hemispherical beam-forming aimed at V2X communication is proposed. This antenna is composed of 4×4 feed-network and 4 rows of CRLH leaky-wave radiating structures that adopt the capacitive inter-element coupled mushrooms. Every single capacitive coupling uses 0.75 pF. We will show beam-forming and enhanced gain performances.Index Terms -Array antennas, Metamaterial, CRLH, Beam-forming, Leaky-wave antennas.
