Folded monopole antenna (FMA) which can cover 2.5/3.5 GHz bands of WiMAX is already reported. In this study, all the three bands of WiMAX are covered by placing a parasitic element in the vicinity of FMA. Furtheremore, two FMAs and parasitic elements are used in order to anlyze the basic characteristics of MIMO antenna using an electromangnetic simulator. As a result, the 3rd band, 5.5 GHz band...

A novel modified printed monopole antenna with variable frequency band-notch characteristic for ultra-wideband (UWB) applications is presented. The proposed antenna consists of a truncated ground plane and a radiating patch with two tapered steps. To generate a notch band at 5–6GHz with good level of band-notch a new T-shaped parasitic element placed on the back layer of the substrate along wit...

Johnna Powell and Anantha Chandrakasan Massachusetts Institute of Technology 50 Vassar St. Rm 38-107, Cambridge, MA 02139 johnna, [email protected] ABSTRACT This paper introduces two antenna designs for Ultra Wideband 3.1-10.6 GHz communication. The primary antenna design is an equiangular spiral slot patch antenna with an outer radius of 2.25 cm. The incorporation of a ground plane enables c...
