Abstract
This paper presents a novel compact dual-band and dual-polarized complementary split-ring resonator (CSRR)-fed substrate-integrated waveguide (SIW) cavity-backed fractal patch antenna for wireless energy harvesting and communication. The proposed antenna is composed of a Giuseppe Peano fractal radiation patch with a backed SIW cavity. To enhance the bandwidth and minimize the dimensions, the CSRR structure is designed to feed the Giuseppe Peano fractal patch orthogonally. A prototype of the proposed antenna is simulated, fabricated and measured. The proposed antenna exhibits good directionality and high cross-polarization level with especially compact size.
Highlights
Microwave power transmission (MPT) transmits power through free-space without the use of wires or cables, which is attractive for applications in oil-less helicopters, 24 h high-altitude platforms and solar power satellites
This paper presents a novel compact dual-band and dual-polarized complementary split-ring resonator (CSRR)-fed substrate-integrated waveguide (SIW) cavity-backed fractal patch antenna, which aims to work simultaneously for wireless energy harvesting and communication
Many via holes spaced along the rectangular opening are drilled in the substrate, constituting SIW cavity, which is the backing of the radiating element
Summary
Microwave power transmission (MPT) transmits power through free-space without the use of wires or cables, which is attractive for applications in oil-less helicopters, 24 h high-altitude platforms and solar power satellites. A dual-band antenna that can be applied simultaneously for wireless energy harvesting and communication with compact size is highly desirable. The traditional waveguide, which is costly with a bulky non-planar hollow rectangular structure and high power capacity, can be synthesized into a planar substrate with metalized slots or even arrays of metallic via posts. The SIW has provided very attractive applications in designing low-cost, low-profile, and highly efficient waveguide microwave printed circuitry, active devices, and antennas. In [6], SIW cavity-backed dual-band circularly polarized (CP) antennas with planar configurations were investigated. A dual-mode SIW cavity-backed triangular ring slot antenna was proposed and developed for dual-band application in [8]. An SIW-fed cavity-backed rectangular patch antenna was proposed in [9], and it was designed to operate in its TE210 mode. The fractal geometries are conducive to the miniaturization of antenna designs and realization of antenna ultra-wideband or multiband characteristics [11,12]
