“…Still, the system's output stays the same in this case [48]. Yang, Sun, & Guo [59] developed a low-cost, series-fed dual-CP antenna printed on a single-layer PCB for MM-wave applications. In the work of Cheng, Wang, & Liu [60], a 94 GHz substrate integrated waveguide (SIW) parallel-plate long-slot array antenna was presented.…”

The investigation into new sources of energy with the highest efficiency which are derived from existing energy sources is a significant research area and is attracting a great deal of interest. Radio frequency (RF) energy harvesting is a promising alternative for obtaining energy for wireless devices directly from RF energy sources in the environment. An overview of the energy harvesting concept will be discussed in detail in this paper. Energy harvesting is a very promising method for the development of self-powered electronics. Many applications, such as the Internet of Things (IoT), smart environments, the military or agricultural monitoring depend on the use of sensor networks which require a large variety of small and scattered devices. The low-power operation of such distributed devices requires wireless energy to be obtained from their surroundings in order to achieve safe, self-sufficient and maintenance-free systems. The energy harvesting circuit is known to be an interface between piezoelectric and electro-strictive loads. A modern view of circuitry for energy harvesting is based on power conditioning principles that also involve AC-to-DC conversion and voltage regulation. Throughout the field of energy conversion, energy harvesting circuits often impose electric boundaries for devices, which are important for maximizing the energy that is harvested. The power conversion efficiency (PCE) is described as the ratio between the rectifier’s output DC power and the antenna-based RF-input power (before its passage through the corresponding network).

A circular-polarized patch antenna with compact size operating at 2.3 GHz band is presented. The antenna utilizes L shaped slot in the radiator in order to achieve circularly polarized radiation pattern. The prototype of the antenna is fabricated and is fed by a 50Ω strip line. The antenna achieves a symmetrical radiation pattern around zenith. The measured impedance bandwidth of |S11| less than-10dB is from 2.3GHz to 2.35GHz and is in good agreement with simulation results. The antenna achieves better cross-polarization isolation of-19 dB and wider 3dB axial ratio beamwidth (ARBW) of-50 0 ≤ ARBW ≤ 45 0 at its resonating frequency. The antenna finds application in modern wireless communication system.

“…With the help of the travelling current on the S-shaped dipole arm [10], AR bandwidth of 60% is achieved with the wide AR beamwidth. In addition, by using series-feed method [11]- [12] and quadrature feed networks [13]- [15], broadband antennas are achieved for the stable unidirectional CP radiation.…”
