“…The FSS reflects the unwanted frequency coming from the antenna, and the maximum gain is achieved if the EM waves radiated from the antenna and the EM waves imitated from the FSS are in the same phase. The gain improvement of FSS loaded antenna is dependent upon the reflection phase (ϕ FSS ) of FSS and height (h) of FSS superstrate from the antenna, extracted from Equation (8). 8) where N = 0, 1, 2, 3, .…”

“…Frequency selective surface (FSS) structure is used for gain, bandwidth enhancement and grating lobe reduction in microstrip antenna, which can reflect or pass the EM waves coming from the antenna. Several gain enhancement techniques have been investigated to enhance the properties of microstrip antenna such as artificial magnetic conductor (AMC) [5], metamaterial [1,6,13], single [8,10], and double-layer FSS [2,7,11]. In [1], a double split ring reflector based on mu-negative characteristic of the metasurface is used for gain enhancement.…”

“…In [7], a double-layer passband FSS is used to influence the gain at ISM band placed over microstrip antenna. In [8], the single-layer passband substrate integrated waveguide (SIW)-FSS is loaded to enhance the gain of a microstrip antenna whereas in [9] an FSS combined with a DRA is used for gain enhancement. In [10], double-side single layer FSS incorporated with chip resistor is used for gain enhancement of a DRA in X-band.…”

In this paper, a modified circular loop Frequency Selective Surface (FSS) loaded on a slot antenna is proposed for sub-6 GHz 5G applications. The proposed FSS reduces the resonant frequency to lower bands of conventional circular FSS without change in its size. The operating bandwidth (−10 dB) of the proposed antenna with polarization-insensitive single-layer FSS varies from 3.6 GHz to 6.1 GHz with an average gain of 7-7.5 dB and a maximum realized gain of 7.87 dB. An FSS superstrate is loaded onto a slot antenna to increase the realized gain up to 4 dB, where the FSS shows desirable electromagnetic wave reflection characteristics over operating bandwidth and can be used in 5G sub-6 GHz band applications.

Herein, design, development, and analysis of ultra-low power sensing energy harvesting modules and their subcomponents for ISM band applications have been studied with a holistic approach in an effort to achieve a feasible and high efficient RF energy harvesting performance. The complete harvester system designed and developed here consists of a zero-bias RF energy rectifying antenna (rectenna), DC boost converters and energy storage super-capacitors. Compared with the counterpart energy sources, the surrounding or transmitted wireless energy has low intensity which requires designs with high efficiency. To achieve a successful harvester performance, rectifier circuits with high sensitivity Schottky diodes and proper impedance matching circuits are designed. Dedicated RF signals at various levels from nanowatts to miliwatts are applied at the input of the rectenna and the measured input power versus the scavenged DC output voltage are tabulated. Furthermore, by connecting the rectifier to a high gain antenna and using a RF signal transmitter, the wireless RF power harvesting performance at 2.4 GHz was tested up to 5 m. The performance of the rectenna is analyzed for both low-power detection and efficiencies. Impedance matching network is implemented to reduce the reflected input RF power, DC to DC converters are evaluated for their compatibility to the rectifiers, and super-capacitor behaviors are investigated for their charging and storage capabilities. The measured results indicate that a wide operating power range with an ultra-low power sensing and conversion performance have been achieved by optimizing the efficiency of the Schottky rectifier as low as −50 dBm. The system can be used for battery free applications or expanding battery life for ultra-low power electronics, such as; RFID, LoRa, Bluetooth, ZigBee, and low power remote sensor systems.

ISM/SRD (Industrial, Scientific and Medical/Short Range Devices) applications typically utilize low power wireless RF communication modules, such as ZigBee, Bluetooth, and RFID. RF Energy Harvesting applications require long-lasting and low profile circuits and limited environmental impacts.A typical RF energy harvester design's main part is a rectenna module. A rectenna consists of a rectifier circuit and an antenna with filtering/matching network.Several techniques have been proposed to improve the efficiency of a rectenna system. 1 As discussed in Ref. 1, the design of a high gain and multiband antenna, and then using it as an array antenna will increase the RF energy captured wirelessly. A voltage multiplier and a multistage rectifier topology will increase the converted DC voltage. Finally, for a passive (non-bias) process, low-voltage zero biased

Herein, it is aimed to design an Active Frequency Selective Surface (AFSS) based high performance reconfigurable filtering antenna (Filtenna). The proposed AFSS unit element is consist of a single PIN diode with a simple microstrip patch design which performance characteristics are varies with the state of the diodes. The proposed unit elements have been used to form an array that is placed at the aperture of a double ridge horn antenna. With the variation in state of diodes, the antenna acts as a Filtenna module to filtering the incoming electromagnetic waves in frequency band of 1.8 to 2.8 GHz. From the experimental results, it is shown that the proposed Filtenna achieves a signal attenuation of 7.3 dBi at 2.1 GHz.
