, 2014 Wireless communication has become an indispensable part of modern life. One of the mostimportant components of wireless communication systems are antennas, termed as "eyes" and "ears" of communication systems. A printed antenna, one of the most commercial antennas, is widely used for civil and military applications, i.e., for communication systems ...
