A Q-Band very broad band on-chip antenna for Q-LINKPAN applications

This paper presents a 45GHz on-chip antenna for Q-LINKPAN applications. The antenna has a simple triangle radiating patch that is fed by a 50-Ω modified coplanar waveguide (CPW) structure. Implemented results denote this antenna has a favorable impedance bandwidth from 40-50 GHz, where nearly omni-directional radiation patterns and stable gain are also obtained and shown. Besides, it has a very compact size of 2.5mm ×2.5mm × 0.26mm, which is fabricated by using a standard 0.18-μm CMOS process. Measured results validate the wide frequency response meets the Q-LINKPAN standard requirement, which is a good candidate for mobile high data rate communication systems.
