The uniplanar implementation of double periodic composite right/left‐handed (DPCRLH) symmetric unit cell is realized using coplanar waveguide and its analysis with parameter extraction are studied. DPCRLH symmetric unit cell is then experimentally validated. The open‐circuited DPCRLH resonator is formed from the DPCRLH unit cell which exhibited five resonance points. The simulated resonant frequencies of the resonator are 1.5494, 2.1968, 3.5072, 5.0438 and 6.089 GHz. A triple‐band antenna is designed from the last three resonant frequencies of the resonator. The antenna is horizontally polarized in all three bands. The measured co‐polarized gain of the antenna at the central frequencies of the three bands are 1.52 dBi (3.59 GHz), 3.67 dBi (5.1694 GHz) and 1.78 dBi (6.0925 GHz), respectively.

“…On the other hand, to realize left-handed nature on a transmission line, a composite right/left-handed transmission line (CRLH-TL) which adds both a series capacitor and a shunt inductor to the original line was first proposed [5]. Then CRLH-TLs consisting of various shapes have been reported [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Left-handed waveguides are constructed by loading capacitive shorted stubs and inductive windows in [6,7], and also by inserting corrugations [8][9][10][11].…”

This paper proposes a composite right/left-handed cylindrical waveguide. Negative permeability is realized by the cutoff TM 01-mode in a hollow waveguide, and negative permittivity is realized by the cutoff dominant TE-mode in a sector waveguide with a ridge. Usefulness of the proposed cylindrical waveguide is verified from the numerical computations of both the dispersion diagrams and the transmission characteristics of the structure with finite-number unit cells. Finally, measurement of the fabricated waveguides is performed for the experimental verification.
