Continuous beam scanning performance of dipole array antenna coupled to meander two-wire parallel transmission line

Abstract

A mechanical beam scanning dipole array antenna coupled to a meander two-wire parallel transmission line is proposed. A meander transmission line is introduced to the proposed antenna in order to suppress its grating lobe without using lumped element inductors. Numerical simulation demonstrates that the proposed antenna is capable of continuous beam scanning ranging from 2°(@ϕ = 0) to 42°(@ϕ = 180°) without grating lobe due to the meander transmission line.
