In this paper, we investigate and compare the radiation characteristics of a planar substrate-integrated Fabry-Perot cavity antenna designed with different unit-cell geometries. The antenna consists of a frequency selective surface (FSS) and a planar feeding structure, which are both lithographically patterned on a high-permittivity substrate. The planar feeding structure is an open-ended leaky-wave...
A single layer and single feed high gain Fabry-Perot cavity type antenna is presented in this paper. The antenna is designed to operate at around 22 GHz so that it can be used for K-band applications. An open-ended leaky-wave slit dipole fed by a coplanar waveguide is printed on one side of the substrate whereas a frequency selective surface made of a circular hole array is defined on another side...
