Eccleston, KW2018-06-292013-01-282013-01-28978-1-4577-1330-92165-4727BFC89 (isidoc)https://hdl.handle.net/10182/9922Low temperature co-fired ceramic (LTCC) is the favored manufacturing technology for millimeter-wave substrate integrated waveguide (SIW) systems. SIW consumes a significant quantity of LTCC conductor material, typically gold or silver, as the width of substrate integrated waveguide is set according to the TE10 mode cut-off frequency. However, the solid conductors forming the top (and bottom) walls of SIW can be replaced by a conducting mesh thereby reducing the amount of precious metals required. Both simulations and experiment of SIWs operating at X-band demonstrate the feasibility of using a meshed conductor. The mesh does not significantly increase passband insertion loss.pp.1244-1246en© IEEEsubstrate integrated waveguideplanar microwave circuitslow-temperature co-fired ceramicConference Contribution - published10.1109/APMC.2012.6421883978-1-4577-1332-3
