1. An apparatus comprising:
at least one touch sensor;
an integrated film that includes at least one antenna; and
a capacitor in series between the at least one antenna and a radio frequency integrated circuit,
wherein:
the integrated film is at least partially disposed on the at least one touch sensor, such that the at least one touch sensor operates as a radiating element for the at least one antenna;
an antenna feed line's resistance between the at least one antenna and a touch panel integrated circuit is at least 300Ω; and
the at least one touch sensor and the touch panel integrated circuit are electrically connected without an in-series inductor.
