Electro-acoustic component, has arrangement of electromagnetic band-gap structures for damping electromagnetic waves in blocking zone

摘要

An electro-acoustic component comprises an arrangement of electromagnetic band-gap structures (Z1,Z2,I1,I2), where this arrangement damps electromagnetic waves in a blocking zone (SB2). A first circuit (F1) has at least one resonator (SR1, SR3, PR1, PR2) and is circuited with a second circuit (F21-F24) which contains the electromagnetic band-gap arrangement.
