(e). The boresight and maximum gain for the all configurations shown if Table II for the IFA arrays and in Fig. 10 for the slot arrays. Loss due to mutual coupling of an IFA array is 0.94 dB for the array on the left long edge, 0.55 dB for the array on the right long edge, 0.42 dB for the array on the top short edge and 0.25 dB for the array on the bottom short edge. Loss due to mutual coupling of a slot array is 0.560 dB for the array on the left long edge, 1.42 dB for the array on the right long edge, 0.06 dB for the array on the top short edge and 0.98 dB for the array on the bottom short edge. Boresight of a top and bottom slot arrays will change when those arrays are combined into an antenna system.
