From: Experimental demonstration of peripherally-excited antenna arrays
a Top view of the fabricated 7 × 7 PEX antenna array prototype which is etched on a Rogers RT/duroid 5880 1oz substrate, showing the different sides of the array A, B, C and D, and the coordinate system used. (Dimensions = 131.4 mm × 131.4 mm × 1.575 mm). b A photo of the near-field scanning experimental setup used, showing the PEX prototype and the waveguide probe using to measure the near-field radiation from the antenna.
