Wide band long slot array antennas

Printed Wide Slot Ultra-Wideband Antenna - InTech - Open slot antenna has limited bandwidth, whereas wide-slot antennas exhibit wider bandwidth. Recently, different printed wide-slot antennas fed by a microstrip line or coplanar wave‐ guide have been reported [7, 8]. Apart from these antennas, monopole like slot antennas have also been reported to have wide bandwidth characteristics [9-11]. IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 54, NO. 2 ...
