Abstract :
In this paper, we designed and tested ESAs with impedance matching circuits having different gain. We succeeded in implementing the circuit which matches the small radiation resistance of ESA to amplifier. Measured results are close to the simulation value. So we proved possibility to design and fabricate ESA with high radiation efficiency.
