Abstract :
A novel type of antenna which combines the leakage nature of the conductor-backed coplanar waveguide (CBCPW) and the parallel-plate slot array is proposed. The structure is simple and uses only one layer of substrate without any via holes. The proposed antenna features wide impedance bandwidth, high front-to-back ratio of the radiation pattern, and is readily expandable into large planar arrays. Simulated and measured data are presented with good agreement.
