The design of a miniaturized CPW-fed rectangular slot antenna over reactive impedance substrate is proposed. Two-dimensional printed periodic circular metallic patches have been introduced on one side of the substrate for designing of reactive impedance substrate (RIS). Instead of conventional metal plate, arrays of periodic circular metallic patches are introduced as backed material for the lower...
This paper presents the design and study of a dual band E-shaped patch antenna for UWB application. The antenna uses foam of 5 mm thickness as substrate, resonates at 5.3 GHz and 7.4 GHz with impedance bandwidth of 760.43 MHz and 1.39 GHz respectively. Better impedance bandwidth of 2.75 GHz (45%) is obtained by incorporating slots in the ground plane. Diversity structure is also realized. The antenna...
