A NOVEL DESIGN AND DEVELOPMENT OF RECTANGULAR MICROSTRIP ANTENNA FOR C TO KU BAND OPERATION

This paper presents the novel design and development of five open stub loaded rectangular microstrip antenna for multiband band operation. The multibands are achieved at C to KU band of frequencies by incorporating five vertically open s tub of equal length at optimum place on the conducting patch. By adding two vertical slots on the patch the impedance bandwidth is enhanced in the upper operating band with minimum change in the lower operating band retaining the nature of broadside radiation characteristics .The proposed antenna may find application in WiMax, radar system applications, satellite communication and VS AT systems and in the frequency range between C and Ku.
