Abstract
It is shown that it is possible to match an antenna having a very low radiation resistance to a 50-ohm coaxial line using an inductive matching post near the base of the antenna. This technique is illustrated using two electrically small self-resonant genetic antennas. The input admittances of these antennas are simulated with and without the matching posts; the antennas are then fabricated and these results are verified experimentally.
