Abstract
A first sector patch and a second sector patch are loaded on a dielectric substrate having any dielectric constant. The circumferences of the first sector patch and the second sector patch are connected to the dielectric substrate by means of vertical shorting walls, respectively. Notches, a coaxial feeding probe, and a shorting pin are loaded on the first sector patch, so that the first three radiation patterns of the antenna are excited, disturbed and aggregated, and radiation null points which can be scanned along with a frequency change are symmetrically generated on a horizontal plane; moreover, addition of the second sector patch realizes a single-direction null frequency scanning function on the horizontal plane.
