Designs of Compact Circularly-Polarized and Polarization Reconfigurable Antennas by Using Quasi-Lumped Quadrature Coupler
碩士 === 國立彰化師範大學 === 電機工程學系 === 102 === Antennas designs based on a compact feeding network are studied in this thesis. First, three quadrature couplers, including a traditional coupler, a size-reduced coupler, and a quasi-lumped coupler, are designed and their performances are investigated. Accordin...
