Antenna spiral planar bụ antenna eji ebufe na ịnata akara eletrọnịkị na-atụgharị na mbara igwe, yana njirimara na ngwa ndị a.

Njirimara

1. Polarization mode: Planar spiral antenna nwere ọnọdụ polarization aka ekpe ma ọ bụ ọnọdụ polarization nke aka nri.
2. Mmekọ nke impedance: Planar spiral antenna nwere ezigbo impedance dakọtara arụmọrụ.
3. Radiation direction: Antenna nwere ezigbo ọrụ ntụzịaka radieshon, yana ntụzịaka radieshon kachasị dị na ntụziaka nkịtị n'akụkụ abụọ nke ụgbọ elu ahụ ma na-egbukepụ ebili mmiri polarized okirikiri.
4. Njiri mara nke na-anaghị adabere ugboro ugboro: dị ka antennas spiral equiangular, nke a na-ekpebi ụdị ya site na akụkụ na anaghị agụnye ogologo ogologo, mgbanwe ugboro ugboro anaghị emetụta àgwà ha, yana ha nwere bandwit dị oke obosara.

Ngwa

1. Ntugharị nlegharị anya: N'ihi ọnọdụ polarization nke aka ekpe ma ọ bụ aka nri na arụ ọrụ ntụzịaka radieshon dị mma, antenna mpi nwere ike ịnata akara elektrọnik n'ụzọ ziri ezi na ntụzịaka pụrụ iche na polarizations maka nyocha nke nghazi ebumnuche na isi mmalite mgbaàmà.
2. Nkwukọrịta satịlaịtị: Enwere ike iji antenna mpi RF mee ihe dị ka ebe nri maka satịlaịtị na-atụgharị uche, na-enye nri nke ọma na-enye akara satịlaịtị adịghị ike na ngwa nnata.
3. ubi ndị ọzọ: Microwave mpi mpi nwekwara ngwa na ultra wideband nkwurịta okwu, radar agha, biotechnology, na ubi ndị ọzọ, dị ka izere nnyonye anya n'etiti ultra wideband nkwurịta okwu na warara na usoro nkwurịta okwu.

Qualwavena-enye antennas spiral planar na-ekpuchi ọnụọgụ ugboro ruru 40GHz. Anyị na-enye antenna mpi uru ọkọlọtọ nke uru 4dB, 5dB, 7dB, yana mpi mpi abụọ nwere ike ime ka ndị ahịa chọrọ.
