چکیده
We attempt to design and fabricate of a 4×4 Butler matrix for short-millimeter-wave frequencies by using the microfabrication process polytetrafluoroethylene (PTFE) substrate-integrated waveguide (SIW) synchrotron radiation (SR) direct etching PTFE addition metal film sputter deposition. First, dimensions SIW rectangular through-holes G-band (140-220 GHz) operation are determined, cruciform 90 ° hybrid coupler an intersection circuit connected matrix. Then, trial fabrication is performed. Finally, validity result verified measuring pattern.

Design of a Low Cost 44 Butler Matrix Fed Antenna Array Partially Loaded with Substrate Integrated Waveguide (SIW)
A low cost 4 4 butler matrix fed antenna array has been proposed for Ku band applications. At high frequencies, the ohmic and dielectric losses are high and also the undesired feed radiation is more in the case of microstrip line feed, therefore substrate integrated waveguide (SIW) has been used to feed the antenna elements. The implementation of SIW technology improved the radiation performa...

متن کاملMillimeter-Wave Chemical Sensor Using Substrate-Integrated-Waveguide Cavity
This research proposes a substrate-integrated waveguide (SIW) cavity sensor to detect several chemicals using the millimeter-wave frequency range. The frequency response of the presented SIW sensor is switched by filling a very small quantity of chemical inside of the fluidic channel, which also causes a difference in the effective permittivity. The fluidic channel on this structure is either e...
