Abstract:
A meanderline loaded antenna configured for stagger tuning, the antenna comprising:a horizontal reference plane; a first vertical radiator adapted with a feed point and having first and second ends, the first end operatively coupled to the reference plane; a second vertical radiator having first and second ends, the first end operatively coupled to the reference plane at a distance from the first vertical radiator; a horizontal radiator having first and second edges, the horizontal radiator located in relation to the first and second vertical radiators so as to define a gap between each edge of the horizontal radiator and the second end of each vertical radiator; and a pair of meanderlines, each interconnecting one of the vertical radiators to the horizontal radiator across the corresponding gap, and each associated with a number of fingers having a length-based order ranging from a shortest finger to a longest finger, wherein the meanderlines are adapted for causing a combination of loop mode and monopole mode current distribution thereby enabling antenna quality factor adjustment substantially independent of antenna gain.
