چکیده
A simple scheme for the realization of terahertz (THz) fundamental-mode closed-stopband composite right/left-handed leaky-wave antennas (CRLH LWAs) is presented. The proposed CRLH LWAs are reconstructed by graphene-based coplanar waveguide (CPW) transmission line supercells. Their shunt inductances achieved narrow graphene strips two unit cell structures halved. designed and confirmed numerical simulations. They also exhibit frequency-scannable behaviors at THz with narrower bandwidth than that conventional CPW without stopbands. Therefore, supercell could further improve performance beam-steering THz.

Improved Composite Right/left-handed Cell for Leaky-wave Antenna
An improved composite right/left-handed (CRLH) unit cell optimized for a leaky-wave (LW) antenna is presented. This CRLH cell consists of a series of one transmission line, an interdigital capacitor, another transmission line and a shunt shorted stub. Introducing the transmission lines, the parasitic self-resonances of the capacitor are shifted outside the operational band, the radiation range ...
متن کاملPlanar Leaky-Wave Antennas
Leaky-wave antennas use a traveling wave to radiate continuously along a radiating aperture in order to produce a focused beam of radiation. Planar leaky-wave antennas are particularly attractive since they use simple dielectric layers and/or metallic screens over a grounded substrate layer. A simple source such as a dipole or slot inside the substrate or on the ground plane excites the leaky w...
متن کاملDouble-side Radiating Leaky-wave Antenna Based on Composite Right/left-handed Coplanar-waveguide
A double-side radiating leaky-wave antenna based on composite right/left-handed (CRLH) coplanar-waveguide (CPW) is proposed. Dispersion diagram of the unit cell is investigated, and balanced property is confirmed. Thus, the CRLH leaky-wave antenna can have backfire radiation due to the left-handed property of the CRLH structure and broadside radiation at the balancing frequency point. The measu...
متن کاملLeaky wave antenna with amplitude controlled beam steering based on composite right/left-handed transmission lines
An antenna comprising two different composite right/left-handed transmission line structures is proposed which enables easy beam steering at an operation frequency of 10 GHz. The composite right/left-handed transmission lines are based on planar, periodically arranged via free unit cells, implemented in microstrip technology. Both transmission lines exhibit the infinite wavelength phenomenon wh...
متن کاملTunable Dielectric Resonator-Based Left-Handed Leaky Wave Antenna
Recently, left-handed (LH) metamaterials have been achieved by arranging an array of TE resonant dielectric resonators (DRs) in a cut-off parallel plate waveguide [1], [2]. Since negative permittivity is provided by the TE cut-off background, the DRs only need to generate the required negative permeability in order to realize a LH metamaterial. This configuration provides a more flexible choice...
