A Phoenix Unit Cell with Linear Polarization for Weather Radar Applications
This paper presents a novel phase-shifting unit cell topology for reconfigurable reflectarray antennas, designed for weather radar applications at a resonance frequency of 10 GHz. The proposed unit cell structure comprises two symmetric parts, each of them consisting in two concentric half square rings surrounding a half square patch. The two symmetric parts are connected to each other with a variable capacitor. This design achieves a wide phase range of 284 degrees, making it good candidate for adaptive beam-forming. Simulation results demonstrate the cell's effectiveness, highlighting its potential in advanced reflectarray antenna systems for improved low-cost radar solutions.
