A novel method of producing and switching multiple beams using double square loop (DSL) antenna is proposed. By switching the feed point, the pattern can be steered at a coarse step of 45?? throughout the 360?? of space and the associated beam can be directed in eight directions, thus offering a wide range of options for modern wireless devices to focus the beam at a desired target direction. Furthermore,...
Single arm rectangular spiral antenna with four open circuit switches over a high-impedance surface (HIS) is proposed for pattern reconfigurable applications. The HIS plane without vias is utilized to achieve a low-profile antenna design with a net thickness of 5.08 mm. This is equivalent to ~ lambdao/17 for the intended operating frequency of 3.3 GHz. By using the possible sixteen switching combinations...
