MaRF waveguides zvishandiso zvinotumira simba kubva kune imwe nzvimbo kuenda kune imwe. Panzvimbo pekuisa simba zvakananga munzvimbo yese seantenna, microwave waveguides inogona kuvharira simba musimbi isina chinhu, izvo zvinoderedza zvakanyanya kurasikirwa panguva yekutumirwa kwesimba. Millimeter wave waveguides inogona kunzwisiswa se antenna yakasimba kwazvo, uye simba rinogona kungopararira mu waveguides chete, uye harigone kuparadzirwa kune imwe nzvimbo.
Kuchinja kweWaveguide ndeimwe yewaveguide, inoshandiswa zvakanyanya munzvimbo dzakasiyana-siyana, kusanganisira asi kwete kungogumira pakutaurirana kwe microwave, radar systems, communication satellites uye microwave radio link equipment. Kune mhando dzakawanda dzekuchinja kwewaveguide, kazhinji dzine performance yepamusoro, typical standing wave VSWR≤1.2 mukati me full waveguide bandwidth, zvinhu zvekutanga zvinosanganisira copper, aluminum, surface treatment methods silver plating, gold plating, nickel plating, passivation, conductive oxidation, nezvimwewo.

Zvimiro:

Chinhu chinowanzoonekwa negwara rekuchinja mafambiro emhepo ndechekuti madoko maviri aya anoshandisa mhando dzakasiyana dzegwara remhepo pakushandura pakati pemhando dzakasiyana dzegwara remhepo. Semuenzaniso:
1. Vashanduri veWaveguide kuenda kumicrostrip: Vashanduri veWaveguide kuenda kumicrostrip vanoshandiswa zvakanyanya mukuona macircuit akabatanidzwa e millimeter wave monolithic uye ma hybrid circuits, pamwe nekubatanidza waveguide kuenda ku planar circuits kuti ive nechokwadi chekuti shanduko pakati pemitsetse miviri yekutumira inoenderana.
2. Kuchinja kubva kuma waveguides ane mativi maviri kuenda kuma waveguides ane rectangular: Ma waveguides ekuchinja akagadzirwa nemachina chaiwo anogona kubatanidza ma waveguides ane mativi maviri kune ma waveguides ane rectangular, zvichiita kuti pave nekurasikirwa kwakaderera uye kuenderana kwakanyanya. Rudzi urwu rwe waveguides rwekuchinja rwakakodzera kuiswa murabhoritari uye kuyerwa kwe double-ridged rectangular waveguides pamwe nemidziyo.
3. Kuchinja kwenzira yekufamba netsoka ine rectangular: Nzira yekufamba netsoka ine rectangular inoshandura nzira yeTE10 zvakafanana munzira yekufamba netsoka ine rectangular kuita nzira yeTE11 munzira yekufamba netsoka ine denderedzwa. Kuchinja uku kwakakosha pakutumira masaini zvinobudirira kubva kunzira yekufamba netsoka ine rectangular kuenda kunzira yekufamba netsoka ine denderedzwa, kunyanya mumashandisirwo anodiwa pakushandura nzira iyi chaiyo.

QualwaveKuchinja kwewaveguide kunofukidza huwandu hwemafrequency anosvika 220GHz, pamwe nekuchinja kwewaveguide kwakagadzirirwa vatengi.
