Small-size CPW silicon resonating antenna based on transmission-line meta-material approach

A small-size zeroth-order resonating antenna based on a composite right/left-handed transmission line (CRLH TL) fabricated on high resistivity silicon substrate using coplanar waveguides (CPW) is proposed. The CRLH TL consists of a series of CPW interdigital capacitors and parallel short-ended CPWs. The predicted and experimental results for return loss, gain and radiation pattern are in very good agreement.
