Modified threedimensional selfcomplementary array antenna over a finite ground plane
Abstract
Attention is given to the design of an unbalanced wideband antenna, having a very simple structure, which is based on the threedimensional, selfcomplementary antenna principle. A method is proposed for the derivation of a unidirectional and constant impedance antenna from a threedimensional selfcomplementary antenna design having several symmetrical radiation lobes. In addition, a theoretical and experimental analysis of the radiation characteristics of a monopoleslot pair with a finite ground plane is given, and it is shown that these characteristics remain almost unchanged when the ground plane is larger than one wavelength in four directions from the center of the antenna pair. A wideband antenna consisting of element pairs spaced at equal intervals and with a length taper is described which exhibits substantial array effect on the gain. The gain is found to be higher than that of a monopole notch array antenna with a ground plane.
