ABSTRACT:
A stub-loop based antenna doublet array having an offset feed and adjustably positioned stub-loops is provided that enables improved isolation of the horizontal versus vertical polarization characteristics from the impedance. Consequently, conventional VSWR adjustments or tuning can be accomplished without significantly impacting the polarization ratios or pattern.
