Strips

Different type of strip lines Microstrip Stripline Co-planar waveguide Grounded coplanar waveguide

Antenna impact on the PCB

Receiver characteristics Specification requires -70 d. Bm Some radio chips down to -90 d. Bm The 10 meter range is not included in Bluetooth specification.

Network Analyser

VSWR (Voltage Standing Wave Ratio)

VSWR Power sent to the antenna should be accepted and not reflected.

Return Loss

Smith Chart is used for matchinng and adjusting antennas

Transmission measurement

3 D radiation pattern

Field regions of antenna

3 D radiation pattern measurement

Radiation Pattern from Bluetooth swivel under development measured in Moteco´s anechoic chamber. A 3 D scan reveals things a 2 D scan never could.
