Abstract :
A dual-mode antenna design, utilizing a combination of differential- and common-mode excitations, is presented. This antenna offers the possibility to complex-combine both modes in order to obtain a near-hemispherical Field of View (FoV) coverage. A Single-Ended (SE) to Mixed-Mode (MM) transformation model is introduced to determine the MM radiation characteristics of this antenna from SE scattering parameters and embedded element patterns. A FoV of ±90°, from zenith, is achieved with a maximum gain variation of 5 dB.
