Micro-acoustic filtenna

A filtenna comprising:

• an antenna configured to have a first resonance frequency associated with electromagnetic oscillations of the antenna;
• and
• one or more acoustic resonators coupled to the antenna, a first acoustic resonator in the one or more acoustic resonators configured to have a second resonance frequency associated with acoustic oscillations of the first acoustic resonator, wherein the filtenna is configured to have a filter transfer function based at least in part on the first resonance frequency of the antenna and the second resonance frequency of the first acoustic resonator.

A method of processing a signal using an antenna circuit configured to at least one of transmit or receive wireless signals over a target operating frequency band, the method comprising:

• filtering the signal with a radiating element included in the antenna circuit, wherein the radiating element is configured to radiate electromagnetic waves and wherein the radiating element has a first resonant frequency different from a center frequency of the target operating frequency band;
• and
• filtering the signal with one or more acoustic resonators included in the antenna circuit and electrically coupled to the radiating element.
