... boundary waves and the regular part of the current, but also the interference of the boundary waves, excited by the opposite edges of the radiating curtain. Boundary waves, when reaching the border of the radiating curtain, are reflected and the resulting boundary waves in finite antenna arrays are the superposition of waves that appear because of multiple re-reflections. Fig 1,c shows the process of re-reflection of the boundary wave excited by one of the edges of the array with the number of radiators N =2 (curve 1 ...

... can be rendered as follows: (2) where — magnetic-field strength of the p -th slot with unit voltage on the k -th slot. After representing the current and voltage in the semiinfinite antenna array as a sum of the corresponding elements in the infinite array and the boundary wave (3) and inserting (3) into (2), we receive the set of equations for determining the voltage and current of the boundary wave at the input of the matching circuits of the radiating elements and the equations for determining the current and ...
