A newly designed pattern reconfigurable Fabry-Perot cavity antenna is presented in this paper. The reconfigurability is achieved by employing a phased array with a reconfigurable feed network as the source of the FPC antenna. The design can switch its main beam direction between ™10° and 10° with respect to the broadside direction from 5.36 GHz to 5.76 GHz. The realized gain of the proposed antenna...
The design of a novel partially reflective surface (PRS) antenna with the capability of beam steering is presented in this paper. The beam steering is realized by employing a reconfigurable PRS structure to achieve a changeable reflection phase as well as using a phased array as the source to excite the PRS antenna. A prototype antenna including the biasing network is fabricated and measured. It achieves...
A novel centre-fed printed reflectarray using windmill elements is presented. The analysis of the structure and computation of the phase curves for the field reflected from the patches, needed for the design of the elements, have been carried out with the commercial software Ansoft HFSS. The reflectarray sample is a 37-elements structure, and the results have shown good pattern behaviour and symmetry...
