Radial-line to coaxial-line junction to a dielectrically sheathed post

An analysis of a coaxial line/radial line junction is presented for the case where the center conductor of the coaxial line extends the full width across the radial line and is completely sheathed in a lossless dielectric. The problem is analyzed by the Fourier transform method using a realistic mod...

Zusammenfassung:An analysis of a coaxial line/radial line junction is presented for the case where the center conductor of the coaxial line extends the full width across the radial line and is completely sheathed in a lossless dielectric. The problem is analyzed by the Fourier transform method using a realistic model for the coaxial excitation. Expressions for the current distribution on the post and the admittance of the junction are deduced. Comparison of theoretical and experimental results show the theory to be very accurate.< >
