Application of the parallel plate canonical problem in predicting diffraction caused by a tape fixed on a ground plane

A new asymptotic high frequency technique is presented expressing the diffraction from the edges of a tape fixed on a ground plane. This technique is applicable to investigating the impact of tapes used to cover the gaps created between adjacent panels forming the reflector of a compact antenna test range (CATR), particularly at millimeter-wave frequencies. Results obtained experimentally in the 90 GHz band show good agreement with prediction based on the proposed method.
