“…An antenna is the first and the most important element of the RF energy harvesting system, and it affects the amount of captured energy from the environment [ 4 ]. Numerous research works have been reported on the antenna for RF energy harvesting purposes to achieve appropriate characteristics, such as high efficiency [ 11 , 12 , 13 ], lower return loss [ 1 , 14 , 15 ] and an omnidirectional radiation pattern with high gain [ 11 , 12 , 16 ].…”

“…Most of the reported materials for the antennas designed for RF energy harvesting are made of conventional printed circuit board (PCB)-based materials such as Rogers, RT/Duroid and FR4 substrates [ 1 , 11 , 14 , 17 ], which is due to the established fabrication concepts from many years ago, low cost, easy fabrication and easily available material.…”

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.

As the size of the antenna often has a significant influence on overall dimensions of the wireless system, its reduction in size becomes a significant challenge. The objective of this chapter is to present new contributions made for reducing the size of the antenna array while maintaining excellent performance. An overview of the antenna array is introduced. Then, two designed and fabricated antenna arrays with compact size and good performances are exposed. The first microstrip patch antenna array is miniaturized using a novel shape of defected ground structure (DGS) etched in the ground plane of each radiating element of the antenna array. While the second one is two antenna arrays which are separated by two magnetic walls of a planar compact electromagnetic band gap (EBG) structure, with the aim to miniature and to reduce the mutual coupling between them, keeping both the antenna arrays separation smaller than 0.6λ5.8GHz. A full-wave electromagnetic analysis had achieved to evaluate the electrical performances of the proposed structures by using HFSS and CST-MWS.
