CPW composite right/left-handed zeroth-order resonance antenna on silicon substrate

The paper presents the results concerning the design, fabrication and measurements for a microwave zeroth order resonance antenna, based on CPW CRLH TLs (CoPlanar Waveguide Composite Right/Left-Handed Transmission Lines). The CRLH TL consists of series CPW interdigital capacitor and parallel connectd CPW stubs. The antenna was fabricated on high resistivity silicon substrate. The theoretically expected results are in very good agreement with the experimental findings, concerning both the return loss and the antenna gain.
