“…LM has been used in several metamaterial structures for various applications [155]- [171], such as microwave absorbers [157]- [163], sensors [164]- [165], antennas and arrays [166]- [167], flexible and reconfigurable metasurfaces [168]- [170] and even THz metamaterials [171]. [160] proposes a switchable metasurface whose absorption spectrum can be switched using LM.…”

This paper reviews the application and technology advancement of Gallium (Ga)-based liquid metal (LM) in highfrequency circuits and antennas. It discusses the material properties of common liquid metals, the fluidic channels used to contain LM and their manufacturing techniques, and the actuation techniques, which are all critical for the design and implementation of LM-based devices. LM's fluidic and pliable nature, together with its excellent electrical, thermal, and rheological (i.e. fluid flow) properties, provides some unique and innovative solutions to flexible/wearable electronics, reconfigurable circuits and antennas. The paper provides a comprehensive review of a wide range of LM-enabled highfrequency circuits and antennas, including: interconnects and transitions, reconfigurable passive circuits (such as resonators, filters, and couplers), switches, phase shifters, reconfigurable antennas, flexible and wearable antennas, and metamaterials (i.e. periodic materials with properties not found in nature). The paper presents various design concepts and implementation techniques, highlights key capabilities, discusses the challenges and opportunities with the use of Ga-based liquid metal materials.

This article presents a bandstop Frequency Selective Surface (FSS) prototype based on square split ring resonators (SSRRs) and a square loop (SL) structure for Ultra Wide Band (UWB) frequency range. Triple band notches are obtained at WiMAX (3.3-3.6 GHz), WLAN (5-6 GHz), and Satellite communication X-band (7.2-8.4 GHz). To make this proposed design work as a band-stop filter, two SSRRs are positioned at the top layer of the substrate to resonate at WiMAX and WLAN frequency band, respectively. A single SL is located at the bottom of the substrate that resonates at satellite communication X-band. Attenuation more than 20 dB is observed at all notched frequencies. An angular stability from 0 • to 40 • is obtained. Compact size, simple structure, low cost material, single layer, easy fabrication, and wide coverage are some of the feathers of this proposed FSS. The dimension of proposed unit cell of FSS is 10 × 10 mm 2 .

In this paper, a novel design of compact microstrip antenna (MA) using an embedded λ/4 resonator is presented. By utilizing the strong coupling between the λ/4 resonator and the radiation patch of MA, the resonant frequency of MA can be decreased. Besides, the λ/4 resonator is embedded in the patch, which does not enlarge the whole size of MA. Therefore, a compact antenna can be realized. In this paper, after the principle is stated, a sample antenna has been manufactured and measured to prove the predicted characteristics of our proposed antenna. The measurement agrees well with the simulation. Hence, the proposed method in this paper is quite suitable for the design of a compact antenna.
