1. An electronic device, comprising:
a radio frequency (RF) circuit region having a first circuit density;
an antenna region comprising a circuit structure defining a waveguide, wherein the circuit structure has a second circuit density less than the first circuit density,
wherein the RF circuit region has a first conductive element, the antenna region has a second conductive element disposed within the waveguide and connected to the first conductive element; and
an impedance matching element configured to compensate a mismatch of impedances caused by the first conductive element and the second conductive element.
