“…With the advancement of modern wireless communication systems, development of high‐gain directional antennas with low‐profile has increasing demand for wireless energy transfer and line‐of‐sight (LoS) communications . Antenna gain can be improved by a lot of methods, such as, using electromagnetic bandgap structure, artificial magnetic conductor, frequency selective surface, metamaterial (MTM) etc. Metamaterial has some unusual and interesting properties, which can be used for the improvement of different antenna parameters.…”

This article presents a novel polarization‐independent metamaterial (MTM) which is used for the design of a low‐profile high‐gain magnetic dipole antenna operating at 9.8 GHz. The MTM is alike star‐shape and shows low impedance property around the frequency 9.8 GHz. The reference antenna, which is the SIW‐based slot antenna acts as a magnetic dipole antenna and it has peak gain of 3 dBi. The metamaterial‐inspired slot antenna has low‐profile, that is, 0.133 λ0 at the frequency 9.8 GHz, and peak gain of 8.24 dBi. At the resonance frequency, more than 5 dB gain improvement is achieved in the proposed design. These results are verified with the fabrication of a prototype antenna and measurements. The cross‐polarized radiation is negligibly altered by this gain enhancement method. The proposed antenna can be used in wireless power transfer and LoS communications.

In this article, a high‐gain antenna for ultra‐wideband (UWB) communication is presented and experimentally validated. Gain enhancement is achieved by employing a frequency selective surface (FSS) screen as a superstrate. The proposed antenna‐FSS arrangement is less complex and realized on a low‐profile FR‐4 laminate. The antenna comprises a circular radiator that is enclosed in a triangular shaped arrangement of slots along with a narrow feed‐line. Lengths and widths of the different sections along with feed are optimized to achieve an ultra‐wide impedance bandwidth. The employed superstrate is an array of modified square shaped FSS (MS‐FSS). Full wave analysis validates its effectiveness in achieving at least 5 dBi gain enhancement of the UWB antenna while maintaining wideband impedance match. Moreover, the antenna behavior is also analyzed by varying periodicity and the distance between superstrate and the proposed slot antenna. This antenna‐FSS arrangement is a suitable candidate for high‐gain UWB portable devices.

“…Metallic reflectors can be used below the antenna for the purpose, however as the spacing between antenna and the reflector is fixed, this kind of arrangement is not capable of producing enhanced radiation over a wide bandwidth. To overcome these problems periodic structures like Partially Reflective Surfaces (PRS) and Frequency Selective Surfaces (FSS) are being used nowadays in place of solid metallic reflectors [14][15][16][17][18]. Alexandros P. Feresidis et al proposed a FSS-based Artificial Magnetic Conductor (AMC) operating at 22 GHz placed surrounding a patch antenna [14].…”
