In this paper, a circularly polarized metasurface antenna for microwave energy harvesting (MEH) is proposed. First, a 4 × 4 metasurface is analyzed and integrated with the microstrip slot based on characteristic mode analysis for broadband, low profile, and high gain metasurface antenna. The measured results show that the impedance bandwidth of the metasurface antenna is 1.82 GHz, the 3 dB axial ratio bandwidth is 0.96 GHz. Subsequently, a wideband rectifier for C‐band is fabricated and measured according complex impedance compression theory. The frequency of efficiency >50% is from 5.1 to 6.3 GHz with 17 dBm input power. Finally, the novel antenna and rectifier are connected as rectenna for MEH, which shows great potential due to the tunability of the polarization mode (right‐handed CP [RHCP]/left‐handed CP [LHCP]) and the flexibility of the structure.

Broadband antennas with a low-profile generating circular polarization are always in demand for handheld/ portable devices as CP antennas counter multipath and misalignment issues. Therefore, a compact millimeter-wave antenna is proposed in this article. The proposed antenna structure comprises two circular rings and a circular patch at the center. This structure is further embedded with four equilateral triangles at a 90° orientation. The current entering the radiator is divided into left and right circular directions. The equilateral triangles provide the return path for current at the differential phase of ±90°, generating circular polarization. Structural development and analysis were initially performed through the characteristic mode theory. It showed that Modes 1 to 4 generated good impedance matching from 20 to 30 GHz and Modes 1 to 5, from 30 to 40 GHz. It also demonstrated the summation of orthogonal modes leading to circular polarization. The antenna-measured reflection coefficient |S11| > 10 dB was 19 GHz (23–42 GHz), and the axial ratio at −3 dB was 4.2 GHz (36–40.2 GHz). The antenna gain ranged from 4 to 6.2 dBi. The proposed antenna was tested for link margin estimation for IoT indoor conditions with line-of-sight (LOS) and non-line-of-sight (NLOS) conditions. The communication reliability with co- and cross-polarization was also studied under these conditions, and the results proved to be satisfactory.

A compact metasurface (MTS) antenna with a dimension of 20 mm Â 20 mm consisting of non-uniform fractional meta-unit (n-MTS) cells has been proposed in this article. The n-MTS shows distinctive electromagnetic characteristics compared to conventional MTS, that is, the E-field surface waves on the n-MTS are singularly co-extending in nature, exhibiting an e-TM 30 mode (e-extraordinary). The higher order modes with n-MTS significantly improves the antenna resonant properties at (5-6) GHz Wi-Fi band. The potential improvement in antenna modal parameters are showcased with numerical approach for validations in proximity to the theoretical quantitative metrics. A MTS antenna array configuration of dimension 40 mm Â 40 mm with a RF power-divider feeding arrangement has been proposed, operating at dualbands (5.45, 6.4 GHz) with radiation gain >8 dBi and radiation efficiency >80% (at dual-bands). The unit cell n-MTS configuration has sharp resonances and unique meta-parameters are achieved at operating frequency, enabling existence of higher-order mode in a low-profile and proliferates for compact antenna design embodiment. The prototype antennas are fabricated and measured, which shows good correlation between simulation and test results, to be implemented in Wi-Fi applications.
