March 2011Doc ID 018585 Rev 11/28 AN3359 Application note Low cost PCB antenna for 2.4GHz radio: Meander design 1 Introduction This application note is dedicated to the STM32W108 product family from STMicroelectronics. One of the main reasons to use a PCB antenna is the reduced overall cost of the radio module. Well designed and implemented PCB-printed antennas have a similar performance to the SMD ceramic equivalence. In general, the footprint for a ceramic SMD antenna is smaller than that for a PCB-printed variant. For a PCB-printed antenna solution, the increased size of the PCB in relation to space required for the antenna means that the radio module is larger cost of the PCB increased. The increased cost of the PCB is smaller and less expensive than a SMD ceramic antenna. The STM32-RFCKIT RF control kit is based on an STM32W108xx RF microcontroller. It implements a PCB-printed antenna to perform RF communications. www.st.com ContentsAN3359 2/28Doc ID 018585 Rev 1 Contents 1Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 1Coordinate system . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 2Layout specification . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 3Impedance matching . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 4Radiation pattern, 3-D visualization . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 5Radiation pattern, 2-D visualization . . . . . . . . . . . . . . . . . . . . . . . . . . . 14 6Performance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25 7Summary . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 26 8Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 AN3359 Doc ID 018585 Rev 13/28 Table 1.Specification of the recommended substrate . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Table 2.Document revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 AN3359 4/28Doc ID 018585 Rev 1 Figure 1.Spherical coordinate system. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 Figure 2.Layout of Meander-like PCB antennae . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 Figure 3.Cross section of the PCB at antennae region. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Figure 4.Part of the ZigBee module's PCB with Meander-like antenna (around scale 4:1) . . . . . . . . 8 Figure 5.Bypassing impedance matching circuitry - direct RF connection . . . . . . . . . . . . . . . . . . . . . 8 Figure 6.Complex impedance of the Meander-like antenna on Smith Chart . . . . . . . . . . . . . . . . . . . 9 Figure 7.Magnitude of the S11 parameter in logarithmic scale (Cartesian plot) . . . . . . . . . . . . . . . . 10 Figure 8.Antenna's Standing Wave Ratio (SWR) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 Figure 9.Three dimensional (3-D) radiation pattern overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 Figure 10.Radiation pattern on Y-Z plane . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 Figure 11.Radiation pattern on X-Z plane . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 Figure 12.Major planes used to visualize 3-D radiation pattern using 2-D plots . . . . . . . . . . . . . . . . . 15 Figure 13.Far field radiation pattern plotted on Y-Z plane . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 Figure 14.normalized radiation pattern on Y-Z plan (Polar plot) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 Figure 15.normalized radiation pattern on Y-Z plane (Cartesian plot)) . . . . . . . . . . . . . . . . . . . . . . . . 18 Figure 16.Far field radiation pattern plotted on X-Y plane . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19 Figure 17.Normalized radiation pattern on X-Y plan (Polar plot) . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20 Figure 18.Normalized radiation pattern on X-Y plan (Cartesian plot) . . . . . . . . . . . . . . . . . . . . . . . . . 21 Figure 19.Far field radiation pattern plotted on X-Z plane . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 22 Figure 20.Normalized radiation pattern on X-Z plane (Polar plot). . . . . . . . . . . . . . . . . . . . . . . . . . . . 23 Figure 21.Normalized radiation pattern on X-Z plane (Cartesian plot) . . . . . . . . . . . . . . . . . . . . . . . . 24 AN3359Coordinate system Doc ID 018585 Rev 15/28 1 Coordinate system For the purpose of this document, the spherical coordinate system illustrated in Figure 1 is used. Figure 1.Spherical coordinate system The PCB module is orientated vertically (plane X-Z), and located in proximity to the origin of the coordinate system. The azimuth angle radiates from the X-axis towards the Y-axis, and the elevation angle radiates from the Z-axis towards the horizontal plane, X-Y. Sometimes, as with geographical and navigational systems, the X-axis is called the "Nord-axis", the Y- axis is called the "East-axis" and the Z-axis is called the "Zenith-axis". Layout specificationAN3359 6/28Doc ID 018585 Rev 1 2 Layout specification PCB antennas, including the electrical parameters of PCB materials used, are layout sensitive. STMicroelectronics recommends using a layout as close as possible to that shown in Figure 2. Figure 2.Layout of Meander-like PCB antennae The electrical parameters and performance of the PCB antenna are also determined by the substrate used, in particular the thickness of the core and dielectric constants .
