Improved antenna measurement techniques using sub-Nyquist sampling and EM modelling

• Develop and validate a sound methodology for the testing of antennas over a range of temperatures.
• Develop and validate a sound methodology that links antenna modelling, sub-Nyquist spatial-sampling measurement-strategies with Electromagnetic-Modelling (EM) based interpolation to give a quantified uncertainty for the result. Validate the methods against traditional technique using both small and large antenna structures. Provide a rule-based approach that relates the measurement throughput improvement to the degradation of the uncertainty, allowing an optimum solution (WP2).
• Develop Optoelectronic Low-reflectivity Field-Sampling Probe for operation at 60 GHz.
• Improve the efficiency of Compact Antenna Test Range (CATR) by reducing the number of measurements needed to achieve the required uncertainty. The RF field variations in the measurement region "quiet zone" will be predicted and verified for 60 GHz operation using a scanning system and the OLFSP developed in this JRP.
