A Dual-Polarized 1-D Wide-Angle Beam-Scanning Phased Array Antenna With High Polarization Purity Based on TGV Technology
This letter presents a dual-polarized series-fed substrate integrated waveguide (SIW) phased array antenna at W-band utilizing through-glass-via (TGV) technology. To overcome fabrication challenges, the TGV-based high-density micro-vias are employed to achieve a 14% reduction in the width of the SIW transmission line (WSIW) compared to traditional PCBs, thereby extending the scanning range. To improve the polarization purity for the performance of beam-scanning, a symmetric butterfly-shaped slot element is applied with a significant improvement in cross-polarization compared with a T-shaped slot. The proposed antenna employs dual-linear polarization synthesized from dual-circular polarizations. The simulated and experimental results demonstrate that both polarizations exhibit sustained 1-D beam-scanning capability over ±60°, confirming operational viability for W-band wide-angle beam-scanning synthetic aperture radar.
