Mumunda wemagetsi emagetsi emagetsi emagetsi, maRF antennas uye microwave antennas anowanzo kuvhiringika, asi pane chaiwo misiyano yakakosha. Ichi chinyorwa chinoitisa ongororo yehunyanzvi kubva pamativi matatu: frequency bhendi tsananguro, dhizaini musimboti, uye maitiro ekugadzira, kunyanya kusanganisa akakosha matekinoroji senge.vacuum brazing.
RF MISOVacuum Brazing Furnace
1. Frequency bhendi renji uye maitiro emuviri
RF antenna:
Iyo inoshanda frequency bhendi ndeye 300 kHz - 300 GHz, inovhara yepakati wave kutepfenyura (535-1605 kHz) kusvika mamirimita wave (30-300 GHz), asi maapplications akaiswa mu <6 GHz (senge 4G LTE, WiFi 6). Iyo wavelength yakareba (centimita kusvika padanho remamita), chimiro chakanyanya dipole uye chikwapu antenna, uye kunzwa kwekushivirira kwakadzikira (± 1% wavelength inogamuchirwa).
Microwave antenna:
Kunyanya 1 GHz - 300 GHz (microwave kusvika millimeter wave), akajairika application frequency mabhendi akadai seX-bhendi (8-12 GHz) uye Ka-bhendi (26.5-40 GHz). Ipfupi wavelength (millimeter level) zvinodiwa:
✅ Submillimeter nhanho yekugadzirisa kurongeka (kushivirira ≤±0.01λ)
✅ Yakasimba pamusoro pehukukutu kudzora (<3μm Ra)
✅ Yakaderera-kurasikirwa dielectric substrate (ε r ≤2.2, tanδ≤0.001)
2. Mvura yekugadzira teknolojia
Kuita kwemicrowave antennas kunoenderana zvakanyanya nepamusoro-yekupedzisira kugadzira tekinoroji:
| Vadivelu Comedy Technology | RF Antenna | Microwave Antenna |
| Kubatanidza tekinoroji | Soldering/Screw fasting | Vacuum Brazed |
| Typical Suppliers | General Electronics Factory | Brazing Makambani seSolar Atmospheres |
| Welding zvinodiwa | Conductive connection | Zero okisijeni kupinda, zviyo chimiro kurongekazve |
| Key Metrics | On-resistance <50mΩ | Thermal yekuwedzera coefficient inoenderana (ΔCTE <1ppm/℃) |
Iko kukosha kweiyo vacuum brazing mune microwave antennas:
1. Oxidation-isina kubatana: brazing mune 10 -5 Torr vacuum nharaunda kudzivirira oxidation yeCu / Al alloys uye kuchengetedza conductivity> 98% IACS.
2. Thermal stress kubviswa: gradient kupisa kusvika pamusoro pemvura yebrazing material (eg BAISi-4 alloy, liquidus 575 ℃) kubvisa microcracks.
3. Deformation control: yakazara deformation <0.1mm/m kuona millimeter wave chikamu kuenderana
3. Kuenzanisa kwekushanda kwemagetsi uye maitiro ekushandisa
Radiation maitiro:
1.RF antenna: kunyanya omnidirectional mwaranzi, kuwana ≤10 dBi
2.Microwave antenna: yakanyanya kurongeka (beam hupamhi 1 ° -10 °), kuwana 15-50 dBi
Mashandisirwo akajairika:
| RF Antenna | Microwave Antenna |
| FM radio tower | Phased Array Radar T / R Zvikamu |
| IoT Sensors | Satellite communication feed |
| RFID Tags | 5G mmWave AAU |
4. Test verification misiyano
RF antenna:
- Tarisa: Impedance yekufananidza (VSWR <2.0)
- Nzira: Vector network analyzer frequency tsvaira
Microwave antenna:
- Kutarisa: Radiation pattern/phase consistency
- Nzira: Pedyo nemunda scanning (chaiyo λ/50), compact field test
Mhedziso: RF antennas ndiyo ibwe repakona reyakajairwa isina waya yekubatanidza, nepo microwave antennas ari musimboti wepamusoro-frequency uye yakakwirira-chaiyo masisitimu. Mvura iri pakati pezviviri ndeiyi:
1. Kuwedzera kwefrequency kunotungamira kupfupi wavelength, zvichikonzera shanduko yeparadigm mukugadzira.
2. Kugadzira maitiro ekuchinja - microwave antennas anovimba nekucheka-kumucheto matekinoroji senge vacuum brazing kuti ive nechokwadi chekuita.
3. Kuoma kwekuedza kunowedzera zvakanyanya
Vacuum brazing mhinduro dzakapihwa nemakambani ehunyanzvi ekubhuroka akadai seSolar Atmospheres ave vimbiso yakakosha yekuvimbika kwemamilimita wave masisitimu. Sezvo 6G ichiwedzera kune iyo terahertz frequency bhendi, kukosha kweichi chiitiko kunowedzera kutaridzika.
Kuti udzidze zvakawanda nezve antennas, ndapota shanya:
Nguva yekutumira: May-30-2025
