Abstract(in English) | The tri-plate transmission line is usually fabricated by etching copper-coated dielectric substrates to support the center conductor. However, the dielectric loss of the dielectric substrates is no longer negligible increasing operational frequencies, and this fact causes difficulty for loss reduction of filters at millimeter-wave frequencies. With this in mind, we devised a new tri-plate transmission line structure to be able to support the center conductor without the dielectric substrates, and a bandpass filter made by only metal strips was designed by using the structure at 30 GHz. The bandpass filter was fabricated by a wire-electrical discharge machine and the performance was evaluated. The insertion loss within a bandwidth of 1.2 GHz was measured to be less than 1.0 dB, and thus a low-loss filter can be developed although it is needed to fabricate with dimensions being more accurate. |
