Abstract : The generalized integral equations for the curtain array are presented so that element length, spacing and radius may vary. The quasi-zero-order theory as originally applied to circular arrays and later extended to include curtain arrays is reviewed. The separation principle which is employed to simplify the integral equations is discussed in detail. A modified quasi-zero-order theory which incorporates approximations to the integrals that are independent of element length and spacing is introduced. Six simple configurations are presented which compare the solutions and the residuals of the vector potential resulting from the original and modified quasi-zero-order theories. A number of single antennas and parasitic couplets for which there is experimental data, is compared with the modified theory. Currents, residuals, and radiation patterns are presented for 4- and 10-element Yagi arrays. (Author)
