An apparatus including an antenna; a first antenna carrier forming a first support substrate for a first portion of the antenna; and a different second antenna carrier forming a second support substrate for a second portion of the antenna. The first and second antenna carriers are coupled to each other. The antenna extends across a joint between the first and second antenna carriers.

Antenna

An antenna radiating element is arranged as at least one coil and defines a first feed port and a second feed port at its opposed ends. There is a third feed port disposed along the antenna radiating element substantially at a radio frequency effective symmetry point between the first and the second radio feed ports. The first and second feed ports are for interfacing a first radio (e.g., RFID/NFC radio) to the antenna radiating element, and the third feed port is for interfacing a second radio (e.g., FM-TX) to the antenna radiating element. The antenna radiating element is configured to function simultaneously as a balanced coil antenna with respect to the first radio and as two parallel half-loop antennas with respect to the second radio.

FM transmission using a RFID/NFC coil antenna

In accordance with one example embodiment of the present invention an apparatus is disclosed. The apparatus includes a cover, a ground plane, a first inductor, and a second inductor. The cover includes a first end and an opposite second end. The cover is configured to operate as a first loop radiator portion. The ground plane is proximate the cover. The ground plane is configured to operate as a second loop radiator portion. The first inductor is proximate the first end of the cover. The second inductor is between the second end of the cover and the ground plane. The cover, the ground plane, the first inductor, and the second inductor are configured to provide a loop radiator.
