Three‐layered circular patch antennas array with UC‐PBG for wider bandwidth and surface wave propagation mode attenuation at X‐band

In this work, a three‐layered antenna array complemented with Uniplanar Compact Photonic‐Bandgap (UP‐PBG) structure is presented, for applications in the X‐band. The proposed array consists of circular patch radiator operating at 10 GHz, where the element is surrounded by UC‐PBG unit cells in order...

Description
Summary:In this work, a three‐layered antenna array complemented with Uniplanar Compact Photonic‐Bandgap (UP‐PBG) structure is presented, for applications in the X‐band. The proposed array consists of circular patch radiator operating at 10 GHz, where the element is surrounded by UC‐PBG unit cells in order to improve the performance of the antenna. By combining the radiator and the UC‐PBG cells, the directivity, gain and polarization are kept, while the parasitic lobes are reduced 50% their magnitude. The bandwidth augments 44% compared to a conventional array, and a diminution of the surface propagation mode is obtained, increasing the radiation efficiency.
