A method for exciting currents in a radiating ground plane over a wide frequency bandwidth is presented. Using a complementary slot in the ground plane excited by a closely spaced monopole (0.008-0.05¿) with 50 Ω input impedance, a wide frequency bandwidth can be achieved to cover multiple radio interfaces. © 2011 Wiley Periodicals, Inc.
