PROJECT TITLE :
A Compact 2.45-GHz Broadband Rectenna Using Grounded Coplanar Waveguide
This letter presents a compact a pair of.45 GHz broadband rectenna using the grounded coplanar waveguide (GCPW). A replacement broadband slot antenna fed by GCPW with a high gain of 10 dBi and a good half-power beamwidth of 60 is designed as the receiving antenna. By planning an input and an output impedance match network, a compact GCPW rectifying circuit primarily based on the voltage doubler principle is proposed, that has broadband performance and is simple to be integrated with the novel GCPW antenna. The receiving antenna and therefore the rectifying circuit are simulated and measured. The measured results of the rectenna agree well with those of the rectifying circuit, which validate the effectiveness of the planning. The microwave-direct current (mw-dc) conversion efficiencies of the rectenna keep over 50p.c within the band from two.two to 2.6 GHz at 13 dBm received power on a load, and the highest efficiency is 72.five%. This rectenna has sensible performances of broadband, high mw-dc efficiency and compact structure.
