“…Since glass integrated with metal grids is widely used as explosion-proof and burglar-proof windows in modern buildings, antennas can be integrated with glass to provide good signal coverage. Researches show the glass-integrated antenna has advantages of styling, light weight, security and reliable [3], and so far the glass-integrated antennas are mainly applied in vehicles at FM/AM radio frequency band [4]. By modifying the metal grid integrated with glass, antenna for the indoor network at higher frequency bands can be designed.…”

Integrate the antenna with the inherent glass structure of the buildings is a method of optimising the deployment of indoor base station. A triple-band glass-integrated grid antenna for indoor communications is presented in this paper. The antenna consists of three concentric square grid structures and is integrated into glass. With the help of characteristic modes analysis (CMA), three optimum operating modes are obtained and excited with single feeding, each resonant frequency can be tuned independently. To demonstrate the concept, a design for GSM at 1.8 GHz, WLAN at 2.4 GHz and low-frequency band for 5G at 3.5 GHz is provided.Keywords-Glass-integrated antenna, grid frame structure, multiband antenna, characteristic modes analysis (CMA).

“…In fact, the high mechanical stability of glass, and its electrical properties, could achieve suitable RF device specification [ 23 ]. Some other applications of glass material for antennas can be found in the automotive industry for radio FM receivers and in high-speed terahertz communication systems [ 24 , 25 ].…”

This paper investigates micromachined antenna performance operating at 5 GHz for radio frequency (RF) energy harvesting applications by comparing different substrate materials and fabrication modes. The research aims to discover appropriate antenna designs that can be integrated with the rectifier circuit and fabricated in a CMOS (Complementary Metal-Oxide Semiconductor)-compatible process approach. Therefore, the investigation involves the comparison of three different micromachined antenna substrate materials, including micromachined Si surface, micromachined Si bulk with air gaps, and micromachined glass-surface antenna, as well as conventional RT/Duroid-5880 (Rogers Corp., Chandler, AZ, USA)-based antenna as the reference. The characteristics of the antennas have been analysed using CST-MWS (CST MICROWAVE STUDIO®—High Frequency EM Simulation Tool). The results show that the Si-surface micromachined antenna does not meet the parameter requirement for RF antenna specification. However, by creating an air gap on the Si substrate using a micro-electromechanical system (MEMS) process, the antenna performance could be improved. On the other hand, the glass-based antenna presents a good S11 parameter, wide bandwidth, VSWR (Voltage Standing Wave Ratio) ≤ 2, omnidirectional radiation pattern and acceptable maximum gain of >5 dB. The measurement results on the fabricated glass-based antenna show good agreement with the simulation results. The study on the alternative antenna substrates and structures is especially useful for the development of integrated patch antennas for RF energy harvesting systems.
