Abstract
Official abstract text for this publication.
In a direction control antenna, a plurality of impedance elements are connected between a ground body and a radiator, a plurality of switches are connected between each impedance element and the ground body, and on/off of a plurality of switches is controlled according to a control instruction from the outside. In this case, by the turned-on switch, a radiation direction and a radiation form are determined according to short circuit positions of the radiator that is short-circuited to the ground body and the number of short circuit positions.
First claim
Opening claim text (preview).
What is claimed is: 1. A direction control antenna comprising: a ground body; a radiator that radiates a radio frequency (RF) signal and that is used as a direction control element of the direction control antenna, wherein a stub is formed at an edge of the radiator and a shape of the radiator is symmetrical; a plurality of impedance elements that are connected between the radiator and the ground body; a plurality of switches that are connected between each impedance element…
