ABSTRACT:
An electrically-short meandered-slot antenna having a plurality of switch-selected resonant frequencies is described. Meander slot sections are substantially parallel, closely coupled, electrically significant, and substantially equal in length to the overall monopole length of the antenna. Switching among resonant frequencies is accomplished with shunt switches across the antenna slot, the switches preferably being powered inductively and selectively at individual frequencies outside the operating band of the antenna.
