“…However, such a design is no longer compact and by no means easy to be fabricated. In [8] [9], an open CRLH TL derived from SIW has been presented, where the series capacitors were inserted as slots in the upper horizontal waveguide wall and bridged by metal tongues in order to achieve large enough capacitance values.

The specialities of a composite right-/left-handed (CRLH) transmission line (TL) are realised in a closed structure with the purpose to utilise its particular phase behaviour while it transports energy with low attenuation. The configuration is derived from the H 10 rectangular hollow waveguide mode concluding in a reproducible and verifiable design, even of the so-called balanced state. Its origin implies inherent shielding and fundamental mode operation as crucial advantages in comparison to many other designs. The dispersion behaviour is validated on two ways and the Bloch impedance is computed and evaluated with respect to matching. The fabricated prototype is light-weight and compact. The simulation results demonstrate low attenuation and they are confirmed by measurements.

“…The interdigital slot etched on the waveguide surface provides the necessary left-handed (LH) capacitance as well as the radiation resulting in an antenna application. It is noted that a CRLH-SIW leaky-wave antenna has been proposed in [9] which requires a multi-layer printed circuit board (PCB) process and is rather complicated to realize. In [32] the CRLH-SIW TLs as well as the coupler are investigated where the propagation properties of the TLs are studied.…”

Miniaturized waveguide slot antennas using negative order resonance are proposed and developed in this paper. The design of these novel resonant-type antennas is based on the study of a composite right/left-handed (CRLH) substrate integrated waveguide (SIW) starting from the dispersion diagram and the equivalent circuit. These proposed CRLH resonators are realized by etching the interdigital slot on the surface of the SIW. The slot acts as a series capacitor as well as a radiator leading to a CRLH antenna application. Two types of slot antennas, which are openended and short-ended, respectively, are proposed and discussed. The short-ended antenna, which represents a quasi-quarter-wavelength resonator, is characterized by a cavity-backed slot antenna thus providing a high gain. On the other hand, the open-ended antenna exhibits a small size owing to a quasi-half-wavelength operation in the left-handed (LH) region. Four antennas with one or two unit cells are fabricated and measured. Compared with the existing CRLH patch antennas and waveguide slot antennas, our antennas show advantages in terms of simplicity, low-profile, high efficiency, easy fabrication and integration with other circuits.Index Terms-Antenna miniaturization, composite right/lefthanded (CRLH), negative order resonance, slot antennas, substrate integrated waveguide (SIW).

Broadband slot array antenna with full‐space steerable pattern in a composite right/left‐handed waveguide

[1] The aim of this paper is twofold. On the one hand, to provide a better understanding of a composite right/left-handed (CRLH) waveguide, going into those aspects of interest for an antenna designer. A longitudinal slot as a radiating element has been considered to be studied and compared with its classic counterpart. On the other hand, to present the new design approach that is needed when using the CRLH waveguide technology to built array antennas. To that end, a slot array antenna has been designed, built, and measured. The simulations and measurements are in excellent agreement, confirming not only the backward-to-forward beam steering and broadband far-field performance, but also the validity of the design procedure used.Citation: Navarro-Tapia, M., J.
