Wide-band broadside radiation from a double metaline system

A linearly polarized (LP) metaline radiates a back-broadside-forward (BBF) scanning beam, where the broadside beam appears at a specific frequency. In contrast, two LP metalines excited in balanced mode form a broadside beam across a wide frequency band. This double metaline system has a gain bandwidth of 31% for the LP broadside radiation. Similar wide… CONTINUE READING
