In the current paper the author has carriedout modeling, simulation and optimization of a quarter-wave step transformer section for a W-band reduced height type IMPATT oscillator by using High Frequency Structure Simulator (HFSS). Also an easy method of designing and optimizing a tapered impedance...
with 2 narrow vertical slots that is fed by a quarter wave A micro strip Patch antenna is a narrowband, wide--beam transformer. Dual-frequency patch antennas may provide an antenna fabricated by etching the antenna element pattern in alternative to large-bandwidth planar antennas, in metal trace...
The quarter-wave transformer feedThe corporate feedReflection coefficientWThis paper focuses on the Sierpinski carpet fractal antenna (SCFA) Array using quarter-wave feed network to increase the gain and impedance matching. The antenna array is designed and simulated by using HFSS software. FR4 glass...
