Abstract
In this paper hexagonal patch shape with hexagonal slot, ultra wideband antenna is proposed. The total dimensions of antenna are 55×43.5mm. Sides of hexagonal patch are taken 13mm each and hexagonal slot sides are taken as 3mm each. The antenna resonates at two frequencies in ultra wideband range (UWB). There is enhancement in BW in upper range ultra wideband frequency from 6.2 GHz to 8.2GHz due to hexagonal slot cut in hexagonal patch. The design is carried out using Computer Simulation Technology (CST) Microwave Studio (MWS) suite. Co-Planar Waveguide (CPW) feed is used to feed antenna.
Highlights
Recent trends demand for Ultra wideband applications require antenna to be designed for ultra wideband range (UWB) applications
Bandwidth and efficiency of a Microstrip antenna depends upon many factors for eg patch size, shape, substrate thickness, dielectric constant of substrate, feed point type and its location, etc

Summary
Recent trends demand for Ultra wideband applications require antenna to be designed for UWB applications. Bandwidth and efficiency of a Microstrip antenna depends upon many factors for eg patch size, shape, substrate thickness, dielectric constant of substrate, feed point type and its location, etc. In this paper hexagon patch shape is used for design of ultra wideband antenna. S = sides of a regular hexagonal patch antenna ae= Effective radius of the circular patch antenna. In this way sides of hexagon are calculated for the design. Hexagonal shape slot is cut in hexagonal patch Due to this slot antenna resonates on two frequencies. Dimensions 55× 43.5mm 13mm each 55× 43.5 mm CPW feed 4.3 3 mm each wideband frequency from 6.2 GHz to 8.2GHz due to hexagonal slot cut in hexagonal patch.
