“…The cavity depictured in Figure 2b is composed of a perfect electric conductor (PEC) surface acting as a conventional ground plane for the feeding source and the PRS. Furthermore, metasurfaces presenting a gradient in phase have been successfully used for steering the radiated beam in FP cavity antennas [28][29][30][31][32][33]. While a variation in capacitance was applied in references [28][29][30][31], a variation of the inductance was used in references [32,33] to produce the phase-gradient in the metasurface.…”

-The engineering of metasurfaces for antenna and sensing applications is investigated. The metasurfaces composed of LC-resonant cells, are designed to achieve either modulated phase or high quality factor resonances. While the phase modulated metasurface applied as a superstrate in a Fabry-Perot cavity antenna, shows the capability to steer the radiated beam to an off-normal radiation, the high quality factor resonant metasurface presents high sensitivity to the presence of substances.

“…Thus this structure has been broadly utilized in the design of some types of antennas such as low profile leaky wave antenna operating at microwave regime with high efficiency and gain in correlation with conventional ground plane. Also adding active HIS (Huang, Wu, Tang & Mao, 2012) elements loaded with varactor diodes to the antennas enables them to beam steering and easy frequency tuning (Guzman-Quiros, Gomez-Tornero, Weily & Guo, 2012;Sievenpiper, Schaffner, Song, Loo & Tangonan, 2003). It is also possible to insert periodic graphene patches as antenna ground.…”

In this work, a single port exponential tapered toothed log periodic antenna based on graphene artificial magnetic conductor (AMC) is suggested for ultra-wideband (1-10) THz operation. The resonance frequency of the proposed antenna can be tuned by changing the connected DC voltage which leads to variation in the chemical potential of the graphene.The radiating toothed log periodic antenna consists of gold patch placed on 25x25 graphene patches which act as an AMC surface unit. Exponential taper is used to satisfy impedance matching between the antenna and the feeder over the frequency range. The simulation results reveal that 90% of frequency range satisfies < −10 when the chemical potential is1eV.

“…It is known that a center-fed PRS antenna will generate a beam at boresight or a frequency-scanned conical beam [6,7]. Recently, with the rapid development of wireless communication technologies, there has been strong interest in beam-scanning PRS antennas that can provide a fixed beam-scanning angle in a specified frequency range [8].…”

In order to obtain beam-scanning in a PRS antenna, tuning elements should be added into the radiating aperture.…”

Abstract-A beam-scanning partially reflective surface (PRS) antenna is presented in this paper. By employing a reconfigurable feed network to a two-element phased array source, the PRS antenna can realize beam steering between −10 • and 10 • with respect to the broadside direction across an overlapped frequency range from 5.35 GHz to 5.76 GHz. Good agreement between the simulated and measured results is achieved, which validates its capability to be a good candidate for the modern communication systems.
