Metamaterial Vivaldi Printed Circuit Antenna Based Solar Panel for Self-Powered Wireless Systems

Abstract

A high-gain wide-band planar antenna with H-Shaped Resonators (HSRs) for Self-Powered wireless systems is proposed in this paper. The proposed antenna consists of four major parts, namely, a grating Vivaldi electrical dipole, a half-ring magnetic dipole, HSRs, and a solar panel reflector. The dipoles are etched from both antenna substrate sides by each half on one side. The HSR structures are etched on a single side of the used substrate to avoid the capacitive coupling effects which cause the radiation efficiency reduction. HSR inclusions are designed and tested numerically to have the desired electromagnetic properties at frequency band of interest. After introducing the HSR inclusions to the antenna structure, the antenna performance is tested numerically and compared to that without HSR inclusions. The fabricated prototype based HSR structure shows an enhanced gain bandwidth product to cover the frequencies from 1.75 GHz up to 7.43 GHz with a gain varying from 9.52 dBi up to 16.71 dBi over the entire frequency range. Finally, an excellent agreement has been achieved between the gathered numerical results and those from the experimental measurements.

Design of a microwave power transmission demonstration system for space solar power station

“…The compositive experiment verified all function as power transmitting, receiving, rectifying, and steering of MPT system. MPT technology is thus driven toward engineering application, such as self‐powered wireless systems 26 and SSPS in‐orbit application. Further works about the MPT system will be focus on improving the integration of transmitting antennas, and it is expected that space power exploration will eventually be realized in the future.…”

Circularly Polarized Metamaterial Patch Antenna Circuitry for Modern Applications

“…The proposed array is constructed from eleven-unit cell that are distributed with a certain separation distance to achieve capacitive coupling effects that magnifies the electrical field fringing and return reduces the antenna size [4]. The individual unit cell is constructed from Hilbert curve fractal geometry to maintain high surface current density within a limited area [3]. The frequency resonance of the individual unit cell can be tuned with a T-resonator structure through controlling the total impedance with a variable capacitor [9].…”

“…The idea of reconfigurable antennas can be traced back to a D. Schubert patent from 1983 [2]. In 1999, the United State Defense Advanced Research Projects Agency (DARPA) funded a project called "Reconfigurable Aperture Program (RECAP)" to look into the subject in applications of reconfigurable antennas [3]. Reconfigurable antennas have also been used in applications such as broadband networking, cognitive radio, MIMO systems, and others.…”

Improvement in the Gain of UWB Antenna for GPR Applications by Using Frequency-Selective Surface

“…e impedance bandwidth of the proposed antenna below −10 dB ranges from 3 GHz up to 7.43 GHz. After the inclusion of HSR (H-shaped resonator), the gain is improved between 9.52 dB and 16.71 dB [42]. A miniaturized UWB microstrip antenna with slotted patch is design for UWB communication.…”
