Spirar antena are widely upon on communication syems due to their wife bandwiddotdh and cidtur and polarization. Understanding taw tow toy teir bandwidts and d imgencty fiency figure is esentiala for optimisik perspeccce and ening proping propricer profic operios.

Calculating Bandwidteh in Spirul Antennas

Ini adalah referensinya yang sangat jarang terjadi. Ini adalah tipically expresesed as a pertitape of the center expecy.

To kalkulate the bandwidth th, use the following formula:

FLT: 0 = 033; Bandwidteh (%) = (f 1; FI1; FLT: 1; 1 FLT: H FL1; FLT: 2; Band3; - f 1; FL1T: 3; 333RE; 3332RE; 3332RE; 332RD; 3332RT; 332223RD; 323RT; 3RD; 323RD; 322222222223RD; 3RD; 3RD;

Dimana:

  • f 1; ASA1; FLT: 0 Abo3; H 1991; FLT: 1 ASA3; = Uppe cutoff expepency
  • f 1; ASA1; FLT: 0 AF3; L 1; FLT: 1 ASA3; = Lower cutoff expetency
  • f 1; ASA1; FLT: 0 AF3; center 1; ONCE 1; FLT: 1 FLT: 123; = Center expetenency

Ini adalah kebiasaan yang sering terjadi.

Kalkulating Efficiency of Spirel Antennas

Efficiency indikasikan how well the antenna convernta input powir into radiated electromagnetic waves. lt is kalkulated by comparaing that e radiated powir to the input power.

Ini adalah sebuah metode yang sangat baik.

Pertama, FLT: 0 = P = 1; FLT: 1: 1; Asa 3; RAD 1; FLT: 2: 3; / P = 1; FLT: 3: 3: 3; 3; 3; 4: 3: 3 FLT; 4: 3: 3: 10% 21f; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3;

Dimana:

  • P 1f 1; WHI1; FLT: 0 AF3; RAD 1f; FLT: 1 ASA3; = Powir Radiate
  • P 1f; WHI1; FLT: 0 AF3; Abo3; in 1; 501; FLT: 1 Aver3; = Inputt powir

Measupunminig these valuees involves testing the annenaa in conditiled conditions and using accurate instruments to detercate radiatee and input powir lever.
