| Onye ndu-mw | Okwu mmalite nke Ultra Wideband Omnidirectional Antenna |
Na-ewebata onye isi microwave tech.,(leader-mw) ultra-wideband omnidirectional antenna ọhụrụ ANT0104. Emebere antenna siri ike ka ọ rụọ ọrụ n'ọtụtụ ebe site na 20MHz ruo 3000MHz, na-eme ka ọ dabara maka ngwa dị iche iche gụnyere nkwukọrịta ikuku, sistemụ radar na ndị ọzọ.
Uru kachasị nke antenna a karịrị 0dB, na ntụgharị okirikiri kachasị elu bụ ± 1.5dB, na-eme ka nnyefe mgbaàmà ntụkwasị obi na agbanwe agbanwe. A na-emewanyewanye arụmọrụ ya site na usoro ± 1.0dB kwụ ọtọ, na-enye mkpuchi dị mma n'akụkụ niile.
ANT0104 nwere njirimara polarization kwụ ọtọ, na-eme ka ọ dị mma maka ngwa ebe a na-ahọrọ nnyefe kwụ ọtọ. Tụkwasị na nke ahụ, VSWR nke antenna ≤2.5: 1 na 50 ohm impedance na-enye ezigbo ndakọrịta ihe na-enweghị mgbama.
Nhazi ya na nke siri ike na-eme ka ọ dị mma maka ime ụlọ ma n'èzí, yana ọrụ omnidirectional na-enye ohere maka njikọta enweghị nkebi na gburugburu ebe ọ bụla.
Ma ịchọrọ ịbawanye ike mgbaama nke netwọkụ ikuku gị, kwalite arụmọrụ nke sistemụ radar gị, ma ọ bụ na ịchọrọ ịhụ na nkwukọrịta a pụrụ ịdabere na ya n'ọtụtụ oge, ANT0104 Ultra Wideband Omnidirectional Antenna bụ ngwọta zuru oke.
