## **4.2** Schematic Layout eee 

Matching components with the MPA.66.A are required for the antenna to have optimal performance in the spaces specified in the schematic below. Additional matching components may be necessary for your device, Taoglas recommends incorporating extra component footprints, forming a “pi” network, for the MPA.66.A.

## **4.6** Copper Clearance = 

The footprint and clearance on the PCB must comply with the antenna’s specification. The PCB layout shown in the diagrams below demonstrates the MPA.66.A clearance area. The copper keep out area applies to all layers that are below the MPA.66.A. 

The copper clearance area should extend to 5.1mm from the mechanical pads to the ground plane. The PCB edge clearance should be 0.2mm.

## Antenna Integration 

The MPA.66.A should be placed in the centre, as close to the edge on the long side of the PCB as possible, to take advantage of the ground plane. The RF trace must maintain a 50 Ohm transmission line. A “pi” Matching Network is recommended for the RF transmission line, the values and components for the matching circuit will depend on the tuning needed. Ground vias should be placed around the transmission line and the copper clearance area.
