Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.

An antenna includes: a dielectric layer; a reference electrode layer on a first surface of the dielectric layer and with a slot therein; radiation structure on a second surface of the dielectric layer. The radiation structure includes a plurality of radiation parts spaced apart from each other, each of which includes radiation elements spaced apart from each other. The plurality of radiation parts in each radiation structure include first radiation part and a second radiation part; and a first microstrip line and a second microstrip line are on the second surface. The first microstrip line is configured to feed power to the radiation elements in the first radiation part, and the second microstrip line is configured to feed power to the radiation elements in the second radiation part. The first microstrip line has a feed direction different from that of the second microstrip line.
