A high-performance 94 GHz planar Quasi-Yagi antenna on GaAs substrate

A high‐performance 94 GHz planar Quasi‐Yagi antenna on a GaAs substrate is presented. The antenna is fabricated on a 100 μm GaAs wafer and has dimension of 1.6 × 2.6 mm2. Experimental results show that this antenna covers a wide bandwidth from 91 GHz to 106 GHz, with the return loss of better than −...

Zusammenfassung:A high‐performance 94 GHz planar Quasi‐Yagi antenna on a GaAs substrate is presented. The antenna is fabricated on a 100 μm GaAs wafer and has dimension of 1.6 × 2.6 mm2. Experimental results show that this antenna covers a wide bandwidth from 91 GHz to 106 GHz, with the return loss of better than −10 dB. An end‐fire radiation pattern is formed, a peak gain of 7.1 dBi, and front‐to‐back ratio of 15 dB at 94 GHz are also achieved. © 2009 Wiley Periodicals, Inc.
