LS band antenna backed by surface wave structure

In this article, a LS band (1.5–2.3 GHz) antenna is presented.Here, the antenna is backed by partial ground and periodic surface wave structure. Both the simulated and experimental result shows that the proposed antenna acquires a bandwidth of 38.8%, that is, 1.5–2.2 GHz and an end fire radiation pattern with a beam width of 108° and maximum gain of 6.5 dbi at 2.1 GHz.
