Title: DIPLEXER AND TRANSMITTING AND RECEIVING SYSTEM
Abstract:
The objective of the present invention is to provide a diplexer which is more compact and lightweight than a conventional diplexer. A diplexer (10) is provided with a filter pair (20), first and second directionality coupling units (30, 40), and first and second converting unit pairs (50, 60). A waveguide comprising these parts (20, 30, 40, 50, 60) is a post wall waveguide in which each of a pair of conductor plates provided on two surfaces of a single dielectric substrate (11) serve as a first wide wall (13) and a second wide wall (12) respectively, and post walls comprising a plurality of conductor posts (211i, 221i, 23i, 311i, 321i, 33i, 411i, 421i, 43i, 511i, 521i, 53i, 611i, 621i, 63i) which penetrate through the dielectric substrate (11) serve as narrow walls (211, 221, 23, 311, 321, 33, 411, 421, 43, 511, 521, 53, 611, 621, 63).
