Abstract

A method to broaden the E-plane radiation pattern of a dipole antenna over a ground plane is proposed. Two parasitic monopole elements with reactive loads are placed in the vicinity of the driving dipole element. Another advantage of this antenna is that these monopoles do not cause cross polarization in the H-plane. Based on the electromotive force (EMF) method, a new procedure that optimizes the load values is developed. Numerical verification by the method of moments (MoM) is provided; additionally, each antenna parameter including the optimum reactive load is obtained. The experiment is also presented to demonstrate the performance.
