“…Though the radar sensing can mitigate an antenna radiation direction misalignment, it is still difficult to always maintain a polarization alignment between TX/RX antennas, which causes serious polarization mismatch loss in wireless power link and deteriorates the RF-to-dc PCEs of an onboard rectenna of whole ground-to-air MPT system. Some recent researches have been reported to overcome the problems of the antenna polarization misalignments [8][9][10][11][12][13]. The work in [8] presents a circularly-polarized (CP) rectenna for a linearly-polarized (LP) wave receiving.…”

“…However, 3-dB polarization mismatch loss always happens, which degrades the maximum wireless power link between TX/RX antennas. In [9][10][11], it demonstrates that a dual-linearly-polarized (DLP) antenna can receive all incidence for the two successive subrectifiers with parallel dc combinations. Accordingly, RF-to-dc PCEs can be relatively sustained regardless of the antenna polarization tilts.…”

This paper presents a linear-polarization-insensitive rectenna for the ground-to-air microwave power transmission (MPT). With an integration of a hybrid coupler and a dual-linearly-polarized (DLP) antenna, a linearly-polarized (LP) incident wave can be decomposed by the antenna polarization tilts into the horizontally-polarized (HP) and the vertically-polarized (VP) components, correspondingly, which are then distributed evenly through the hybrid coupler as the inputs of two successive lumped rectifiers. Thus, RF-todc power conversion efficiencies (PCEs) of the presented DLP rectenna maintain insensitive to its incident LP polarization tilts. An aperture-coupled feeding mechanism and lumped matching networks are employed to enable the compact DLP rectenna design for practicality. Both theoretical analysis and experimental results validate that the RF-to-dc PCEs of the DLP rectenna keeps stable high regardless of its LP polarization tilts, which demonstrates a prospect for the ground-to-air MPT applications.

“…The most used configuration for a conditioning circuit is the half-wave rectifier, but there are other, more complex configurations that are worth mentioning. For instance, the authors of [13] present a full-wave rectenna, formed by two concentric squared patches attached to a full-wave rectifier. The results show an efficiency in the rectifier of less than 34% for an input power of 1 mW.…”

This paper presents a radiofrequency (RF) energy harvesting system based on an ultrawideband Archimedean spiral antenna and a half-wave Cockcroft-Walton multiplier circuit. The antenna was proved to operate from 350 MHz to 16 GHz with an outstanding performance. With its use, radio spectrum measurements were carried out at the Telecommunication Engineering School (Universidad Politécnica de Madrid) to determine the power level of the ambient signals in two different scenarios: indoors and outdoors. Based on these measurements, a Cockcroft-Walton multiplier and a lumped element matching network are designed to operate at 800 MHz and 900 MHz frequency bands. To correct the frequency displacement in the circuit, a circuit model is presented that takes into account the different parasitic elements of the components and the PCB. With an input power of 0 dBm, the manufactured circuit shows a rectifying efficiency of 30%. Finally, a test is carried out with the full RF energy harvesting system to check its correct operation. Thus, the RF system is placed in front of a transmitting Vivaldi antenna at a distance of 50 cm. The storage capacitor has a charge of over 1.25 V, which is enough to run a temperature sensor placed as the load to be supplied. This demonstrates the validity of the RF energy harvesting system for low-power practical applications.

A single‐layer differential‐fed dual‐band filtering antenna for WLAN application

In this letter, a single‐layer differential‐fed dual‐band filtering antenna for wireless local area network application is proposed. The proposed antenna consists of a square patch, and two pairs of stepped impedance resonators (SIRs). The lower operating passband is realized by exciting the square patch with a pair of differential ports. Then, a pair of SIRs is connected with the radiating edge of the square patch to introduce another resonance, thus forming the upper passband. And a radiation null is simultaneously produced to enhance the frequency selectivity between the two passbands. Moreover, another pair of SIRs is utilized to connect with the nonradiating edge of the square patch, which generates an additional high‐frequency in‐band resonance and a radiation null to further improve the bandwidth and frequency selectivity of upper passband. The developed prototype was fabricated and measured to verify the design concept. The measured results are in good agreement with the simulated ones, demonstrating that it exhibits −10 dB fractional impedance bandwidths of 3.68% and 7.35%, maximum realized gains at boresight direction of 5.5 and 8.7 dBi, and cross‐polarization levels smaller than −30 dB, in lower and upper passbands, respectively.
