Control circuitry may be used to adjust transmit power levels for wireless signals, may be used to tune antennas, and may be used to adjust other settings for the wireless circuitry. The electronic device may have a coupler interposed between an antenna and wireless transceiver circuitry.

The coupling may be capacitively in order to affect the level of coupling or to optimize the driving point return loss. The presence of the dielectric in the slot allows the use of a shorter slot for a given wavelength.
