W-Band Magnetoelectric Dipole Phased Array Antenna Based on the TGV Technology

This paper introduces a phased array antenna design utilizing the TGV (Through Glass Via) process and provides an Antenna Measurement Method. The antenna utilizing a glass substrate with a thickness of 350 um. All vias in the antenna structure have a diameter of 50 um, while the BGA balls possess a diameter of 200 um. The dimensions of the 8 × 8 antenna array are 14.6 × 14.6 mm
