Network parameters of a waveguide broad wall-slot radiator

On the Equivalent Radius of a Radiating Slot in Impedance Calculations

“…The magnetic field H has been expressed in the form of a double integral in terms of half-space dyadic Green's function [2]. The integration of the quadruple integral, so obtained, has been reduced to a closed from expression containing summation of sine and cosine integrals using simplifying approximation.…”

“…Considerable investigations have already been carried out on the evaluation of admittance of radiating slot using variational [1][2][3] as well as moment method [4] formulations. The specific advantage of variational formulation is that it enables evaluation of the parameters of the complex equivalent circuit [1,3].…”

“…The formula contains half-space dyadic Green's function [2]. A close form expression for the quadruple integral has been derived [2] for slots resonating near half wavelength making considerable simplifying approximations.…”

Resonance and Parametric Analysis of Planar Broad-Wall Longitudinal Slot Array Antennas

“…However most of these analyses were carried out for a single slot element. Few literatures are also available on slot array [2,3,4,5,6,7,8,9,10,11,12,13,14].…”

Rigorous and Fast Convergent Analysis of a Rectangular Waveguide Coupler Slotted in Common Wall

“…On the other hand, Levy [5] established the synthetic theory of multiaperture couplers based upon them. Besides these methods the various variational techniques [6,7], the method based upon 'selfreaction' [8] and the moment method [9][10][11][12][13][14] have been presented.…”
