lr = loopRectangular X-Y tekisligida to'rtburchaklar halqali antenna hosil qiladi.
Odatiy bo'lib, o'lchamlar 53 MGts ish chastotasi uchun tanlanadi.
misol
lr = loopRectangular(Name,Value) bir yoki bir nechta nom-qiymat juftligi
argumentlari bilan belgilangan qo'shimcha xususiyatlarga ega to'rtburchaklar
aylana antennasini yaratadi. Nom - bu xususiyat nomi va Value - mos keladigan
qiymat. Ism-qiymat juftligi argumentlarini Ism1, Qiymat1, ..., NameN, QiymatN
sifatida istalgan tartibda belgilashingiz mumkin. Belgilanmagan
xususiyatlar
standart qiymatlarini saqlab qoladi.
LoopRectangular ob'ekt xy-tekisligidagi to'rtburchaklar halqali antennadir.
Pastadir qalinligi tenglama bo'yicha ekvivalent silindrli pastadir diametriga bog'liq.
t=2d=4r
, bu erda:
d - ekvivalent silindrsimon pastadirning diametri
r - ekvivalent silindrsimon pastadirning radiusi
Berilgan silindr radiusi uchun ekvivalent kenglikni hisoblash uchun cylinder2strip
yordam dasturidan foydalaning. Standart dumaloq halqali antenna musbat y o'qida
oziqlanadi. Y o'qining nuqtasi pastadirning ichki va tashqi perimetrining o'rta
nuqtasidir.
