Abstract :
The design steps for a novel cylindrical electronic bandgap antenna in the X-band are given. Simulation results, based on a FDTD modeller are also presented as an aid to designing the physical antenna. The antenna demonstrated high directivity in the H-plane. Measurements on a prototype achieved 54% fractional bandwidth with an average gain of 8 dBi and 17.5 dB front to back ratio in the azimuthal plane.
