ANT0625 Planar Spiral Antenna
| Onye ndu-mw | Okwu Mmalite nke Planar Spiral Antenna |
Ma ị bụ ọkachamara na-eme ihe nkiri, onye na-eweta ihe ngosi ma ọ bụ onye na-ahụ maka ọdịyo, teknụzụ igwe igwe Chengdu., (leader-mw) UHF planar helix antennas bụ ezigbo enyi na sistemụ igwe ikuku UHF gị. Kwuonụ maka mfu mgbaàmà na mgbagha ọdịyo - site na antennas anyị, ị nwere ike ịtụ anya nnyefe ụda na-agbanwe agbanwe na nke doro anya.
Nrara anyị raara onwe anyị nye ihe ọhụrụ na ịdị mma pụtara ìhè n'akụkụ ọ bụla nke antennas helical planar UHF anyị. Anyị ghọtara mkpa nkwukọrịta ọdịyo a pụrụ ịdabere na ya, anyị chekwara antenna a ka ọ gafere ihe a tụrụ anya ya. Nweta ihe dị iche maka onwe gị wee welie ntọala igwe okwu ikuku gị site na iji antennas UHF planar helix anyị.
Were arụmọrụ igwe okwu ikuku gaa n'ọkwa ọzọ site na iji antenna helix planar UHF anyị. Tụkwasa ntụkwasị obi na nka na ntinye aka anyị na ịdị mma iji were nkwukọrịta ọdịyo gị gaa n'ogo ọhụrụ.
