Integrated and Miniaturized Quasi Yagi D-Band Antenna in Glass Interposer

This paper proposes a quasi-Yagi antenna in D-band, integrated in a glass interposer. Proposed antenna has a wide impedance bandwidth covering 110-170 GHz, with 4.78 dBi gain at 140 GHz, ideally suited for handset applications for 6G. Glass interposer provides an opportunity for more compact integration by means of glass panel embedding. Challenges in end-fire antenna measurements over 100 GHz are also discussed and a probe-station based return loss and end-fire gain measurement system is proposed. A separate method using an envelope detector circuit is presented for measuring the normalized radiation pattern and results are compared against simulations.
