Design and fabrication of multi-fingered lines and antenna

Abstract

The trend of any maturing electrical technology is toward miniaturizing, lighter weight, lower cost and increased complexity with several functions in a single chip. To achieve a remarkable circuit area reduction, it is needed to use artificial transmission lines which have similar behavior to transmission line but with reduced physical dimensions by incorporating with lumped elements.Successful antenna design with proximity feed a novel I -shaped proximity feed U-slot rectangular patch antenna based on differing stub lengths is presented. The microstrip dipole with the conventional feedline and the other with the photonic bandgap (PBG) structure feedline were investigated electromagnetically coupling (EMC) between the feed line and the dipole in transverse configuration. All the dimensions and the patterns are directly influenced on the design of bandwidth, efficiency, return loss and the center frequency of the dipole. The PBG structure microstrip feedline is not only remarkable reduced in physical dimension also the better bandwidth than the conventional microstrip feedline.
