Hybrid radio frequency / inductive loop antenna

An apparatus comprising:

• a ground plane;
• a radio-frequency radiator;
• a feed post conductively connected to the radio-frequency radiator;
• a shorting post, wherein the shorting post is connected to the radio-frequency radiator;
• and
• a near-field communications (NFC) tag including an NFC circuit and
• a multi-turn inductive loop configured to couple electrically with the radio-frequency radiator, the multi-turn inductive loop either in conductive contact with the radio-frequency radiator or not in conductive contact with the radio-frequency radiator, the radio-frequency radiator at least partially overlapping the turns in the multi-turn inductive loop, wherein:
• the multi-turn inductive loop is conductively connected with the NFC integrated circuit and configured to inductively couple with a near-field magnetic field to provide power to the NFC circuit,
• the NFC circuit, when powered, is configured to broadcast information stored within the NFC circuit, and
• the multi-turn inductive loop of the NFC tag, the radio-frequency radiator, the ground plane, and the feed post together form a planar inverted-F antenna configured to produce and receive electro-magnetic radio-frequency signals, wherein the multi-turn inductive loop of the NFC tag serves as a radiator extension to the radio-frequency radiator when producing and receiving the electro-magnetic radio-frequency signals.
