433MHz PCB Antenna 400-490mhz Ukuxhumana

Kwethulwa okusha kwethuna kwakamuva kubuchwepheshe bezokuxhumana - the 400-490mmhz antenna. Ngomklamo wayo ohlukile nezici zokusika, le antenna isethwe ukuguqula indlela ohlala uxhumekile.

Ifaka uhla lwemvamisa lwe-400-490mhz, le antenna inikezela indawo ebanzi yokuhlanganisa amakhono wokuxhumana okuthuthukisiwe. Noma ngabe ubandakanyeka ekuxhumaneni ochwepheshe noma komuntu siqu, le antenna iqinisekisa ukuhanjiswa kwesiginali okuthembekile nokusebenzayo.

Nge-VSWR ye- <= 2.0, le antenna iqinisekisa ukulahleka kwesiginali okuncane futhi ihambisa ukusebenza okuhlukile ngisho nasezindaweni eziyinselele. Lokhu kusho ukuthi ungathembela kule antenna ukuhlinzeka ukuxhumana okucacile nokungaphazamiseki ngaso sonke isikhathi.

Ukufakwa kokufakwa kwe-antenna kwe-50ω kunika amandla ukuhambisana okungenamsebenzi ngamadivayisi ahlukahlukene okuxhumana. Ungaxhuma ngaphandle kwe-antenna kule mishini yakho ekhona ngaphandle kokuhlupheka.

Izwa ukukhuliswa okunamandla kwesiginali ngokuzuza kwe-3DBI. Lokhu kuqinisekisa ukuthi amasiginali akho aqinile futhi azinzile, avumela ukucaciselwa okuthuthukile nobubanzi. Yithi kahle ukuxhumeka okubuthakathaka futhi okungathembekile - Jabulela isipiliyoni sokuxhumana esingenamthungo nge-antenna yethu engu-400-490mhhh.

Idizayinelwe ukusetshenziswa kalula, le antenna ine-polarization ethe mpo elula ukufakwa nokuma. Manje, ungamisa i-antenna yakho ngokushesha nangendlela efanele, ukonga isikhathi nomzamo.

Isisindo esingu-1 nje gram, le antenna ingasindi futhi iyaphatheka, okwenza kube lula ukuthwala lapho uya khona. Ubukhulu bawo be-Lxwxt baka-32x7x0.4mm buye bube nento elungele ukufakwa okuqondayo.

Ngaphezu kwalokho, le antenna iza nobude bekhebula le-10 cm. Kodwa-ke, uma udinga ubude bekhebuli abenziwe ngokwezifiso, singakwazi ukwamukela izidingo zakho ezithile. Umgomo wethu ukukunikeza isixazululo esivumelanayo esihlangabezana nezidingo zakho zokuxhumana.

Ekuphetheni, i-antenna yethu engu-400-490mhh ihlanganisa ukuqina, ukusebenza, kanye nokusebenziseka kalula. Ngobubanzi bawo obujwayelekile, ikhwalithi yesiginali ehlukile, kanye nobude bekhebuli elenzakalelayo, le antenna iyindlela ephelele yazo zonke izidingo zakho zokuxhumana. Hlala uxhumekile kunanini ngaphambili nge-antenna yethu ethembekile futhi esebenza kahle 400-490mhmhz.
