Title:
COLLECTIVELY LAMINATED SUBSTRATE IN WHICH DUMMY WAVEGUIDE IS FORMED
Document Type and Number:
WIPO Patent Application WO/2015/111609
Kind Code:
A1
Abstract:
A collectively laminated substrate is provided with N (N is an integer of 4 or more) pattern layers (L1-LN), a dummy waveguide (4) which penetrates the pattern layers in the lamination direction thereof, a conversion part (5) which is formed in the pattern layer and performs a interconversion between an electric signal and a radio wave transmitted/received via the dummy waveguide, and a ground pattern (GP) which is formed in the pattern layer and covers the periphery of a waveguide forming portion (NP). The collectively laminated substrate is characterized by being provided with an antenna (PT) which is formed in the waveguide forming portion of the pattern layer, a first via group (7) which is formed around the waveguide forming portion and composed of a plurality of vias that allow continuity between the ground patterns formed in the first layer and the second layer among the pattern layers, and a plurality of vias that allow continuity between the ground patterns formed in the N-1th layer and the Nth layer among the pattern layers, and a second via group (8) which is provided around the waveguide forming portion and closer to the outer periphery side than the first via group and composed of a plurality of vias that allow continuity between the ground patterns formed between the second layer and the N-1th layer among the pattern layers.
