A Multiband Strip Line Antenna with Half Ground Structure

In this paper the radiation characteristics of designed antenna is presented under simultaneous excitation of both ground and patch. The designed antenna operates at multiple frequency bands in 1–100 GHz frequency range. The first four resonating modes have the fractional bandwidth of 29.8%, 8.54%, 16.23% and 12.6% with order by in the frequency range of 2.9-3.9 GHz, 9.5-10.35 GHz, 15.15-17.95 GHz and 20.45-23.2 GHz respectively. The practical implementation of the proposed antenna is suitable for WiMAX (3.5 GHz), satellite communication (S, X, Ku, Ka-band), vehicle speed detection, closed range targeting radar, SHF, RF engineering and millimeter waves (30–100 GHz). With the utilization of half ground structure the designed antenna averts a major surface-wave loss to obtain the multiband behavior for the given design structure. The presented strip line antenna has reasonably good gain and low VSWR $\pmb{(< 2)}$ for all operating bands.
