In this contribution, we present the design of a power-selectivity horn filtenna based on the use of a nonlinear Split Ring Resonator (SRR). In particular, in order to obtain a nonlinear behavior of the SRR, we load its external gap with a pair of Schottky diodes, which require a not negligible power level to be activated. Inserting the resulting nonlinear resonator inside the throat of a horn antenna, we show that both matching and radiating properties exhibit or do not exhibit a notched-band, depending on the operating power level.

Abstract
In this contribution, we present the design of a power-selectivity horn filtenna based on the use of a nonlinear Split Ring Resonator (SRR). In particular, in order to obtain a nonlinear behavior of the SRR, we load its external gap with a pair of Schottky diodes, which require a not negligible power level to be activated. Inserting the resulting nonlinear resonator inside the throat of a horn antenna, we show that both matching and radiating properties exhibit or do not exhibit a notched-band, depending on the operating power level.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
