Abstract:
A strip line feeding apparatus comprising:a first dielectric substrate, on one surface of which a strip conductor pattern is disposed, and on the other surface of which a first ground conductor pattern is disposed; a second dielectric substrate, on one surface of which a second ground conductor pattern is disposed, the first and the second substrates are disposed one over another so as to form a strip line so that the first and second ground conductor patterns are disposed at the outsides of the strip line; a through-hole for inner conductor, which is connected with the tip portion of the strip conductor pattern and is penetrating the first dielectric substrate; through-holes for outer conductor, which are disposed around the through-hole for inner conductor and are connecting the first and second ground conductor pattern disposed on the upper and under surfaces of the strip line; and a signal feeder comprising a signal conductor and a ground conductor, the signal conductor is electrically connected with the strip conductor pattern through the through-hole for inner conductor, and the ground conductor is electrically connected with the first and second ground pattern through the through-holes for outer conductor; wherein a serial high impedance portion is disposed near to the connecting portion between the strip conductor pattern and the through-hole for inner conductor, and wherein the through-hole for the inner conductor elongates to penetrate the second dielectric substrate.
