Title:
STRUCTURAL BODY, PRINTED BOARD, ANTENNA, TRANSMISSION LINE WAVEGUIDE CONVERTER, ARRAY ANTENNA, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/125784
Kind Code:
A1
Abstract:
A structural body comprises: a first conductive plane (1); a plurality of second conductive planes (4) provided so as to at least partially face the first conductive plane (1); and a transmission line (6) disposed between the first conductive plane (1) and the second conductive planes (4), electrically connected to one of the first conductive plane (1) and the second conductive planes (4) via a conductive connection portion (5), provided so as to face the other one of the first conductive plane (1) and the second conductive planes (4), and having an open end. Unit structures including at least the second conductive planes (4), the transmission line (6), and the conductive connection portion (5) are disposed repeatedly.
