Figure 2 displays the measured and simulated radiation efficiency of VJ 6040 over frequency. circuit. In this case the antenna can be fixed to any 150 MHz band within the UHF range. The 3D planes of VJ 6040 are defined in figure 3. Figure 2. Radiation Efficiency vs. Frequency Figure 3. VJ 6040 3D Plane Definition

- Mounting of antennas on a printed circuit board should be done by reflow soldering. The reflow soldering profiles are shown
- In order to provide the adequate strength between the antenna and the PCB the application of a dot of heat cured epoxy glue
glue could be Heraeus PD 860002 SA. The weight of the dot should be 5 mg to 10 mg. Figure 6. VJ 6040 Footprint Figure 7. Soldering IR reflow with SnPb solder
