NEW TECHNIQUES FOR INCREASING ANTENNA BANDWIDTH WITH IMPEDANCE LOADING [PDF]
Progress In Electromagnetics Research B, 2011 New methods are presented for increasing the bandwidth of wire antennas using impedance loading. This paper extends the seminal Wu-King theory of the internal impedance proflle that produces travelling-wave only current modes on a center-fed dipole antenna. It also presents a numerical optimization methodology based on Central Force Optimization, a new
