- Abstract
In this paper a novel design of compact microstrip UWB antenna with step impedance microstrip line is proposed.The antenna consists of a rectangular patch with slits on the top face and a partial ground with slots at the rear end. The antenna with dimension of 34 mm x 36 mm (L x W) is fabricated on FR-4 epoxy dielectric with relative permittivity of 4.4. The designed antenna has the capability of operating between 3 GHz to 10.26 GHz with a 7.26GHz bandwidth (fh-fl). The proposed antenna has Omni-directional radiation pattern on most of the operating band. Radiation pattern is measured in antenna anechoic chamber. Feed line used has characteristic impedance of 50 Ω. The proposed antenna is anaylzed in both frequency and time domain to check its appropriateness for UWB applications. SMA female connector is used for feeding. Antenna parameters such as return loss and radiation pattern show reasonable agreement with the simulated results.
