Abstract : The simultaneous integral equations for two arbitrarily located parallel antennas are first decoupled into two independent integral equations and then each is solved by two different methods: A five-term current approximation method and a conventional numerical method. In the five-term method, the current is represented by five trigonometric functions, three for symmetric(even) and two for antisymmetric(odd) currents. Typical current distributions and input admittances are obtained for half-wave and full-wave antennas in nonstaggered, in 45 degree echelon and in collinear arrangements. For the nonstaggered case, the results predicted by the two methods agree with each other and with experimental data. For the other two arrangements, no experimental data are yet available. However, the two theoretical methods agree quite well. The five-term method will be extended to a general array of N parallel elements in another report. (Author)
