“…The study of the frequency response is carried out form 0 ο to 180 ο at the step of 5 degree The respective rotations and its frequncy response, and its reflection coefficient will be discussed below. [1] shows that the frequency response we got from rotating the metasurface of the designed antenna is similar to that of the frequency response of the antenna by changing its substrate.…”

Abstract-A frequency-reconfigurable antenna designed using metasurface (MS) to operate at around 5 GHz is studied and proposed. The frequency-reconfigurable metasurfaced (FRMS) antenna is composed of a simple circular patch antenna and a circular MS with the same diameter of 40 mm and implemented using planar technology. The MS is placed directly atop the patch antenna, making the FRMS antenna very compact and low profile with a thickness of only 3.048 The MS consists of rectangular-loop unit cells placed periodically in the vertical and horizontal directions. Simulation results show that the operating frequency of the antenna can be tuned by physically rotating the MS around the center with respect to the patch antenna. The MS placed atop the patch antenna behaves like a dielectric substrate and rotating the MS changes the equivalent relative permittivity of the substrate and hence the operating frequency of the FRMS antenna. Measured results show that the antenna has a tuning range from 4.76 to 5.51 GHz, a fractional tuning range of 14.6%, radiation efficiency and a realized peak gain of more than 80% and 5 dBi, respectively, across the tuning range.

“…Due to their low loss and subwavelength thinness, some metasurfaces have been used as the superstrate or substrate to improve the performance of reconfigurable antennas [18][19][20][21]. These tuning mechanisms are still based on changing their equivalent electrical length, which requires extremely high tunability of the metasurfaces.…”

In this article, a new approach was proposed to tune the operation band of a waveguide antenna over 4 GHz. By loading an elaborately designed metasurface, the standing‐wave field in the waveguide was switched to a new distribution. This could shift the operation band to a new one. A sample antenna integrated with the metasurface was manufactured and measured. Both simulation and experimental results demonstrate that using abrupt reflection phases to control the antenna operation band is an effective approach. Also, the tuning method proposed here can be applied to other antennas to achieve higher tunability. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1218–1222, 2017
