Abstract :
A compact two-way power combining antenna is presented which radiates in-phase signals while dissipating the out-of-phase signals in an internal lumped resistor. A transmission line model illustrates the operation and gives first order values for the antenna design. Measured radiation patterns for odd and even mode excitation demonstrate the isolation achieved.
