ABSTRACT:
A symmetrical printed meander dipole antenna includes a dielectric board including a ground plane; a first antenna trace line disposed on a first portion of the dielectric board and in electrical contact with the dielectric board, the first antenna trace line including a plurality of first vertical meandered traces; a second antenna trace line disposed on a second portion of the dielectric board and in electrical contact with the dielectric board, the second antenna trace line including a plurality second vertical meandered traces, wherein the first and second plurality of vertical meandered traces are symmetrical to each other; and an inductor in contact with the first and second antenna trace lines for tuning the impedance of the symmetrical printed meander dipole antenna.
