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

Abstract

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-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-m 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.

Synthesis of carbon-11-labeled imidazopyridine- and purine-thioacetamide derivatives as new potential PET tracers for imaging of nucleotide pyrophosphatase/phosphodiesterase 1 (NPP1)

“…SPE technique is fast, efficient and convenient and works very well for the O-methylated ether tracer purification using the phenolic hydroxyl precursor for radiolabeling. 13,24,25 The radiosynthesis was performed in an automated selfdesigned multi-purpose 11 C-radiosynthesis module, allowing measurement of specific activity at EOB during synthesis. [17][18][19] On line determination of specific activity at EOB is accurate when reverse-phase (RP) high performance liquid chromatography (HPLC) is used as purification method.…”
