Abstract
The invention relates to a circularly polarized reconfigurable antenna integrated with an adjustable phase-shifting power divider. The antenna includes a first dielectric substrate, a second dielectric substrate, the adjustable phase-shifting power divider, a grounded metal plate, a main radiation sheet, and a parasitic radiation sheet. The adjustable phase-shifting power divider and the ring-shaped main radiation sheet are printed on the upper surface of the first dielectric substrate. The grounded metal plate is printed on the lower surface of the first dielectric substrate. The second dielectric substrate is a cylinder, and the parasitic radiation sheet is printed on the upper surface thereof. The adjustable phase-shifting power divider is connected with the main radiation sheet. The first dielectric substrate is separated from the second dielectric substrate and fixed by a plurality of insulating studs. The circularly polarized reconfigurable antenna integrated with the adjustablephase-shifting power divider, which is provided by the invention, has the advantages that (1) the characteristics of left-handed circular polarization and right-handed circular polarization are realized under the same antenna aperture, and the antenna has a circularly polarized reconfigurable function; (2) the switching speed is fast; the insertion loss is small; the control is simple; and (3) theantenna is easy to process and manufacture, and low in cost.
