Antenna solutions provider Laird Technologies has developed an FM antenna solution that can be incorporated directly inside a handset device, offering improved performance, minimal size, ease of installation and low cost. Called RadioAnt antenna, it provides a combination of FM, impedance matching and signal amplification. The internal active FM antenna circuit provides performance similar to or better than a passive corded headset, said the manufacturer. The shape and size of the radiating element is small and customized to each device, while the size of the mating ASIC is less than 6 x 6 mm. This antenna eliminates the need for a corded headset extending from a handset to enable FM reception and it allows the use of a Bluetooth wireless earpiece for personalized FM radio reception or use of the handset's speakerphone option to provide an external FM experience.

The RadioAnt is a high performance antenna operating across the entire FM frequency range of 88 — 108 MHz with a minimum gain of -32/-46 dBi. Polarization is linear and nominal impedance is 50 Ohms. Besides FM radio, the use of RadioAnt greatly improves the user experience when devices such as MP3 and satellite radio players are operated in conjunction with an FM re-transmission method.

The RadioAnt is ideal for handsets, gaming devices, consumer devices and wearable wireless. Production volumes will be available in the second quarter.
