Design and implementation of frequency reconfigurable microstrip patch antenna for wireless power transfer applications
Objective
To design and develop a compact frequency-reconfigurable patch antenna integrated with a complementary spiral resonator and rectifier circuit for efficient multi-band wireless power transfer and low-power IoT applications.
Abstract
This paper presents a miniaturized frequency-reconfigurable patch antenna for wireless power transfer (WPT) applications. The proposed antenna integrates a tri-turn square-shaped complementary spiral resonator (3-SCSR) into the ground plane to achieve significant size reduction and multi-band operation. Three PIN diodes are embedded within the 3-SCSR structure to dynamically control the effective inductance and capacitance, enabling four distinct operating modes, including single-band, dual-band, and tri-band configurations. The antenna operates over a wide frequency range from 0.205 to 1.7 GHz, covering VHF, UHF, ISM, GSM, and L-band applications. Designed on an FR-4 substrate with compact dimensions of 50 × 50 × 1.6 mm³, the antenna achieves a peak gain of 2.84 dBi. A voltage-doubler rectifier with a radial stub matching network is also implemented, achieving an RF-to-DC conversion efficiency of 50% at an input power of −10 dBm, making the proposed rectenna suitable for low-power IoT applications.
