Figure 3-4 is a design suggestion. The designer is cautioned that even though this
design can be copied, the final product will require tuning. There are many factors that
determine the performance of a PCB antenna: thickness of the copper layer, thickness
of the PCB material, choice of the PCB material (e.g., FR4), and choice of the passive
components used in the impedance matching circuit. The PCB antenna dimensions are
not critical. Once the design has been tuned, what is important is the consistency of the
manufacture.

PCB ANTENNA DIMENSIONS
Figure 3-5 shows the simulated three-dimensional plot of the radiation patter from the
antenna. Figure 3-6 shows the two-dimensional plots.
