In this paper, a novel microstrip antenna is designed, fabricated and experimentally verified for operation in various bands like GPS, WI MAX and WLAN bands. This microstrip patch antenna is based on a DSP antenna design with U-shaped slots and resonant strip to achieve the wideband operation required to meet the specifications. The effect of variation of dimensions and locations of the Uslots ...

For the purpose of wideband operations, a bow-tie slot antenna fed by a coplanar waveguide (CPW) is investigated. The design was realized using a tapered metal stub introduced in the middle of the bow-tie slot. The modified structure shows wider bandwidth over the conventional bow-tie slot antenna. Parametric study of this new antenna results in a design procedure that helps design this class o...
