how to create a slot line in the multilayer substrate, and is achieved by this method, as a separate slot or antenna multilayer printed circuit including at least one slot line is used

摘要

The present invention, at least a first conductive layer, a dielectric layer and a second conductive layer a method for realizing a short-circuit slot line on the multilayer substrate, the method comprising the the steps of etching a slot line (2) having an electrical length L to the first conductive layer, slot lines of the first conductive layer Around the first of the first band having an electrical length L1 L portions comprising the steps of: a (5a) etched, first with an electrical length L2 L around the slot line of the first conductive layer etching the second portion (5b) of the band, a step of etching the second band of the loop shape having an electrical length L3 to the second conductive layer (7), one end of the second band ( Connect the 8a) to a first portion of the first band, the steps of the other end of the second band (8b) is connected to the second portion of the first band, to form a conductive loop including. This method is especially used in order to realize the separation slot line and the slot antenna.
