We all know that when a radiating device is coated with a higher-than-air dialectric material, one effect is a shortening of the radiating element.
What if a portion of the radiating element were dialectrically coated. Two cases come to mind: 1. What if the OUTER section (where the current flow is low) of a dipole were coated? Could this be used to physically shorten an antenna without leading to the LOW Z and LOW Bandwidth effects normally associted with shortened antennas? 2. What if half (say) of the longitudinal surface of a dipole's radiating element were coated with dialectric material, leaving the other half "looking" into free space?
