Abstract
Future antenna will be used to a growing extent for multipurpose applications and thus require operation over wide bandwidths. Especially, planar antennas have been studied to achieve wide bandwidth characteristic for many years.

In this paper, two novel designs for CPW fed wide band slot antennas are presented. In microwave and millimeter wave applications, aperture antennas fed by coplanar waveguide have several useful properties, such as wider bandwidth, better impedance matching, easier integration of solid state active devices and lower radiation losses. The impedance matching and the radiation characteristics of the antennas were studied by using method of moment technique.

One of the proposed slot antenna is consisted of two triangle slots. The triangle slot antenna has small metal inserts of the triangle type for impedance matching. Return loss and the radiation patterns are simulated. The measured 10 dB bandwidth is 2.76:1.

The other proposed slot antenna has new bow-tie slot which is combined with four /2 rectangular slot. The measured 10 dB impedance bandwidth is 1.91:1.
