Abstract
A stagger tuned meanderline loaded antenna is disclosed. The antenna meanderlines are configured for manipulating the antenna's current null, which enables a combination of loop mode and monopole mode current distribution. The antenna quality factor can be adjusted substantially independent of antenna gain to achieve an extended Chu-Harrington relation.
