APPARATUS FOR TRANSMITTING AND/OR RECEIVING MICROWAVE RADIATION

摘要

Gain characteristics can be achieved by displacing the position of maximum amplitude to a base region of the antenna but maintaining a lesser amplitude peak in the central region. This is as shown in continuous lines in Figure 3A. Also the phase distribution is changed so that the phase lag increases relatively slowly in a lower base region and relatively fast in the central and upper regions of the antenna. This is as shown by the continuous line of Figure 3B. This continuous line has a distinct bend in the upper half of the base region in contrast to the two bends 1 and 2 of the conventional phase distribution shown in chain dotted lines.
