Coplanar waveguide (CPW)-FED circular slot antenna for W-band and imaging system applications
2011
Using a coplanar waveguide (CPW) feed with a short-circuiting stub, the fed circular slot antenna for W-band operation is presented.The obtained results show that the impedance bandwidth, which is determined by 10 dB return-loss of the proposed slot antenna, can reach to 21% with the center frequency at 94 GHz (80 GHz–100 GHz), and the gain achieves 3.05 dBi at 92 GHz with good radiation performance. © 2011 Wiley Periodicals, Inc.
