1. An electronic device comprising:
at least one antenna;
a filter connected with the at least one antenna and configured to pass a signal of a specific frequency band among signals transmitted and received through the at least one antenna; and
a processor connected with the filter and configured to control the filter to pass the signal of the specific frequency band,
wherein the filter includes:
a first substrate;
a second substrate facing the first substrate;
a first group of electrodes disposed inside the first substrate;
a second group of electrodes disposed inside the second substrate;
a first transducer electrode including a first group of lines extending in a first direction on the first substrate;
a second transducer electrode including a second group of lines extending in a second direction opposite to the first direction on the first substrate and disposed to alternate with the first group of lines; and
a power supply configured to apply voltages to the first group of electrodes and the second group of electrodes,
wherein the processor is configured to cause at least one of the second group of lines to be separated from the first substrate, by controlling the power supply to apply the voltages to the first group of electrodes and the second group of electrodes based on a frequency of a signal to be passed through the filter.
