Abstract

When the beams are to be formed in the directions of switching points of the microstrip array plates, two microstrip array plates associated with the switching points are used, and deviation in the phase caused by the arrangement of the two is corrected using a half-fixed phase shifter. Therefore, sufficiently large gain is obtained in all directions inclusive of boundary directions in each of the portions of the antenna array in which the gain was very small so far.
