Abstract :
In this paper, the aperture X-band antenna with a hybrid dielectric insertion has been proposed. It is shown that the use of cylinders with different permittivities inside the dielectric matrix and a specific topology in their location gives rise to the significant extension of the operational frequency band up to 2.3GHz and varying the elevation angle of peak directivity in the H-plane.
