Enhanced gain metamaterial-based Leaky-wave beam-forming antenna for the V2X communication

In this paper, a (Composite Right/ Left Hand) CRLH Leaky-wave two-dimensional 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.
