Electromagnetically coupled (EM fed) microstrip patches have their feed structure fabricated on a thin substrate located between the patch antenna and its ground plane as shown in Figure 1. This dual layer design has two main advantages over conventional single layer microstrip antennas. First, spurious radiation from the feed network can be reduced by decreasing the height and increasing the dielectric...
Electronic devices are commonly tested for their susceptibility to radiated signals which they may be exposed to during normal operation. A reverberation chamber is well suited to perform this type of testing because it can expose the device under test to a radiated signal from all polarization and incidence angles. Testing devices by exposing them to a narrow-band or CW signal has been well documented...
