Antenova's innovative printed circuit board (PCB) internal antenna module design enables effective wireless FM radio transmit/receive function without the need for an external headset antenna or unsightly external retractable antenna. 30 x 5 x 1.5mm FM Antenna Module The M10385 is an active antenna module consisting of Antenova's patent pending FM antenna with a matching circuit and low noise amplifier (LNA) in a small 30 x 5mm package, with the convenience of a standard surface mount device (SMD). Top View - Antenna Side Bottom View Typical Mount The M10385 is capable of transmitting/receiving FM frequencies from 87.5 - 108 MHz and is intended to be planar mounted at the edge of the host PCB for minimum PCB space requirement. A minimum clearance of 2mm between the antenna and the host PCB ground plane is recommended for the best FM signal reception.

The transmission measurement was taken at pad M1 on the FM module. In this example the results show that the FM module is immune from any effect of an active GSM antenna, maintaining at least -50dB isolation across all bands. Note: Measured Isolation will depend on details of the placement of the cellular antenna with respect to the FM module.

The matching circuit will require one component and the following pad layout should be designed into the device so the correct circuit can be installed: Example land pattern for module showing routing and position of matching component.shown below: The module is externally matched with a single component: * Component needs to be High Q wire wound inductor * Size 0603 * Value range 0 - 470nH Note: The precise value for the matching circuit component will vary depending on the size of the PCB, surrounding components and plastic case. The antenna should be measured before selecting suitable matching components. Antenova M2M offers a matching service on request. Contact sales@antenova-m2m. com for further information. Matching may also be solved by performing an active listening test by tuning into FM broadcasts across the band, and score the quality of the stations in a listening test. Testing different values of Inductor (0-470nH) and increase or decrease the value according to the quality of reception. This is only a comparative test but can give a very accurate guide to the tuning if performed repeatedly in the same test conditions. Gerber files of the module footprint are available from Antenova M2M on request. Please contact sales@ antenova-m2m.com for further details.
