1. An antenna-equipped connector comprising:
a plug having separate conductive portions and configured to be received by an audio output jack of an electronic device;
a jack configured to connect to the conductive portions of the plug via respective of at least two conductive lines;
an antenna connection node that branches from a branching point on one of the at least two conductive lines;
an antenna connected to the antenna connection node;
a matching circuit connected between the branching point on the one of the at least two conductive lines and the antenna connection node, the matching circuit being configured to impedance match the one of the at least two conductive lines with the antenna, the matching circuit comprising a coil and a capacitor in parallel; and
a countermeasure element configured to reduce effects of earphones or a headset on the antenna and disposed on the one of the at least two conductive lines between the jack and the branching point.
