Host interface The host PCB requires the mating connector which is the I-PEX MHF (UFL) receptacle. The location should be close to the chip/modules pin for the RF. Any feed from this receptacle should be maintained at 50Ω impedance. 8.2. Transmission line • Must have a characteristic impedance of 50Ω. • Length should be kept to a minimum. • Is recommended to be a co-planar waveguide: log on to Antenova.com and try our Transmission line calculator to easily calculate the dimensions most suited to your requirements. • Should have DC blocking capacitor (e.g. 220pF) placed in line to protect the RF front end. 9. Mechanical fixing The antenna uses 3M 468MP adhesive on the reverse side of the FPC. The antenna has an easy access split line to peel off to reveal the adhesive side. It is designed for a one time fix to a clean smooth surface. The antenna is keyed with two 1mm locating holes for easy positioning.

SRFI068-PS-1.01 Antenna integration guide We recommend the following during the design phase to maximise antenna performance and minimize noise: • • • • Minimum 4 layer PCB Route signals and power internally where possible Flood all layers with ground Knit ground on all layers together with plenty of vias Follow placement guidance carefully, in addition Antenova provide technical support to help you through all stages of your design.

Antenna placement For FPC antennas the host PCB size is not critical to performance, however consideration must be given to placement. Using six spatial directions, as shown below, the antenna should ideally maintain a minimum of three directions free from obstruction in order to radiate effectively. Where there are obstructions (e.g. PCB, metal parts, battery etc.) a minimum clearance should still be maintained. These minimum clearances are described later in this section.

SRFI068-PS-1.01 Orientation of FPC The orientation of the FPC with respect to the host PCB should be defined depending on the unit. The proximity of the GND will have an influence on the antenna so the PCB location relative to the antenna should be considered. The FPC will normally be placed in one of the three following options for orientation. In each option a distance (d) is the critical dimension to consider. The diagram below shows the minimum value of (d) for each. Other obstructions may increase this dimension. Vertical mounted FPC Cable + Connector d ≥ 3mm PCB Co-planar to PCB d ≥ 15mm Planar to PCB (Same plane) d ≥ 3mm a n t e n ova.com 10 DATASHEET: FERA 11. SRFI068-PS-1.01 Hazardous material regulation conformance The antenna has been tested to conform to RoHS and REACH requirements. A certificate of conformance is available from Antenova’s website. 12.
