Mayelana nalolu hlelo lokusebenza

Ingabe ufuna insiza ephelele yokuqonda ama-Antenna kanye ne-Wave Propagation? Lolu hlelo lokusebenza luklanyelwe ukusiza abafundi, onjiniyela, kanye nezingcweti ukuba baqonde imiqondo eyinhloko ngokushesha, lunikeze umhlahlandlela ophelele wokulungiselela ukuhlolwa, ukulungela inhlolokhono, nokufunda okujulile.

Ngezihloko ezingu-135 ezihlanganisa izahluko ezingu-5, lolu hlelo lokusebenza lunikeza amanothi anemininingwane, imidwebo, izibalo, namafomula ukuchaza imigomo yezimpondo, ukusabalala kwamagagasi, kanye nobuchwepheshe obuhlobene. Kungakhathaliseki ukuthi ulungiselela ukuhlolwa noma udinga ireferensi yomsebenzi wochwepheshe, lolu hlelo lokusebenza liyithuluzi lakho lokufunda eliwujuqu.

Izici Eziyinhloko:
135 Izihloko Ezahlukweni Eziyisi-5: Ihlanganisa izihloko eziningi mayelana nezimpondo nokusakazwa kwamagagasi, alungele onjiniyela nabafundi.
Amanothi Aningiliziwe Nemidwebo: Imiqondo ichazwe ngokucacile ngemidwebo ewusizo nokumelwa okunemifanekiso.
Ukulungiselela Isivivinyo Nezingxoxo: Kulungele ukubukezwa okusheshayo nokuqonda izihloko eziyinkimbinkimbi.
Iselula Ilungiselelwe: Ilungele ukutadisha usohambeni.

Izihloko Ezihlanganisiwe:
1. Isingeniso sama-Antenna
Uhlolojikelele lwethiyori ye-antenna kanye nemiqondo eyisisekelo.
Izinhlobo zezimpondo: Isotropic, isiqondiso, i-omnidirectional.

2. Amapharamitha we-Antenna
Iphethini yoMsebe: Izifunda zenkundla, ukushuba kwemisebe, ubude be-beamwid, ukuqondisa.
I-polarization: Izinhlobo ezahlukene ze-polarization nokusebenza kahle.
Inzuzo ye-Antenna: Ubudlelwano phakathi kokuqondisa nendawo esebenzayo.
Umkhawulokudonsa nokusebenza Kahle: Amamethrikhi angukhiye okusebenza kwe-antenna.

3. Izinhlobo Nemiklamo ye-Antenna
I-Loop Antennas: Iluphu encane kanye ne-dipole yamagnetic engapheli.
I-Microstrip Antennas: Idizayini, isakhiwo, kanye nezinzuzo.
I-Antenna Arrays: Amalungu afanayo afanayo alandelanayo, ama-arrays ahlukaniswe ngezigaba, i-broadside, ne-end-fire array.
I-Dipoles & Folded Dipoles: Ukucushwa okubalulekile kanye nezakhiwo.

4. Imiqondo ye-Antenna Ethuthukisiwe
I-Loop Radiation Encane: Ukumelana nemisebe, ukumelana ne-ohmic, namapharamitha akude.
I-Rhombic & Long Wire Antennas: Idizayini nezinhlelo zokusebenza.
I-Ferrite Loop Antennas: Ukusetshenziswa kanye nezici ezithile.
Ukucushwa Kwe-Array: Uhlu lomugqa we-N-elementi, isiqondiso semisebe ephezulu, namanull.

5. Ukusakaza Kwegagasi
I-Fris Transmission Equation: Ukuze uthole amandla esignali ebangeni.
I-Radar Range Equation: Ukuqonda ukusebenza kwe-radar.
Imithelela Yomhlaba Emisebeni: Ukuthi umhlaba uwathinta kanjani amaphethini wezimpondo.
Imiphumela Yokuvinjelwa: Ithonya lokubambezeleka kwesikhathi kuma-antenna amafushane we-dipole.

Kungani Khetha Lolu hlelo lokusebenza?
Ukufakwa Okubanzi: Funda yonke into kusukela kuthiyori ye-antenna kuya ekucushweni kwamalungu afanayo okuthuthukile kanye nezimiso zokusabalalisa amagagasi.

Amanothi Acacile, Alula: Izincazelo ezinemininingwane kodwa okulula ukuziqonda ezinemidwebo namafomula asekelayo.

Ilungele Abafundi Nochwepheshe: Kungakhathaliseki ukuthi ulungiselela izivivinyo noma udinga nje izinto eziyisithenjwa ezisheshayo, lolu hlelo lokusebenza luklanyelwe ukufunda nokubuyekeza ngempumelelo.

I-Mobile Optimized: Funda ngejubane lakho ngokuqukethwe okuthuthukisiwe kweselula nemifanekiso, noma ngabe ukuphi.

Izici:
Izihloko Ezihlakaniphe Ezahlukweni: Ukuhlanganisa okuphelele ngezahluko ezihlelwe kahle.
Isixhumi esibonakalayo Esisebenziseka kalula: Isakhiwo esilula nokuzulazula okulula.
Izihloko Ezibalulekile Zokuhlolwa: Kugxilwe emiqondweni eyinhloko yokuphumelela ukuhlolwa.
Iselula Ilungiselelwe: Idizayinelwe ukufunda kweselula okungenamthungo.
Ukufinyelela Ngokushesha Kuzo zonke Izihloko: Ukufinyelela ngokuchofoza kanye kuzo zonke izihloko nezinto ezihlobene.
Lolu hlelo lokusebenza luzoba usizo ekubhekiseni kuyo ngokushesha, lukusize ubuyekeze yonke imiqondo eyinhloko emahoreni ambalwa ngaphambi kokuhlolwa. Hlala uphezulu ezifundweni zakho futhi uqhubeke ufunda ngokuzikhandla.

Esikhundleni sokusinika isilinganiso esiphansi, sicela usithinte nganoma yimiphi imibuzo noma iziphakamiso. Siyayazisa impendulo yakho ngezibuyekezo ezizayo!
