Micro-acoustic multiband filtenna

A method of processing a signal using an antenna circuit, the method comprising:

• filtering the signal with a radiating element included in the antenna circuit, the radiating element being configured to radiate electromagnetic waves and to have a first resonance frequency;
• filtering the signal with at least one acoustic resonator included in the antenna circuit and electrically coupled to the radiating element, the at least one acoustic resonator being configured to have at least one second resonance frequency;
• filtering the signal with a first filter branch electrically coupled to the radiating element and the at least one acoustic resonator, the first filter branch being configured in combination with the radiating element and the at least one acoustic resonator to have a first operating frequency band;
• and
• filtering the signal with a second filter branch electrically coupled to the radiating element and the at least one acoustic resonator, the second filter branch being configured in combination with the radiating element and the at least one acoustic resonator to have a second operating frequency band different from the first operating frequency band.
