Quasi- Yagi antenna arrays are widely used in 5G networks due to their ir high gain and directivity. Accurate calculations are essential for designing effective antenna systems. This article provides a step by -step guidee te perforom these calculations.

Understanding Quasi- Yagi Antennas

A Quasi- Yagi antenna consists of a drinn element, directors, anda reflector. These contents work together te electromagnetic energy in a specific direction, improwing g signal emphth and quality in 5G applications.

Krok 1: Determiny Operating Częstotliwość

Te first step is to identify thee target frequency for thee 5G network, typically ine thee range of 3.3 GHz to 3.8 GHz. Thi frequency influences thee dimensions of thee antenna contexents.

Step 2: Calculate Wavelength

Te długości fali ((lambda)) i s calculated using thee formula:

(lambda = frac {c} {f})

where (c) is the speed of light (approxiately ately 3 x 10 indis1; indis1; FLT: 0 indis3; indis3; 8 indis1; indis1; FLT: 1 indis3; indis3; m / s) and (f) is the frequency in Hz.

Krok 3: Determine Element Lengths

Te delfiny element length is typically about half the flonegth ((lambda / 2)). Directors are usually a bit shorter, andthee reflectol tor slightly longer.

For example:

  • Driven element: (lambda / 2)
  • Kierunki: przybliżony 0,45 (lambda)
  • Reflektor: przybliżony 0,55 (lambda)

Step 4: Calculate Spacing Between Elements

Spacing between elements feeffects the antenna 's directivity. Typically, spacing is about 0.1 to 0.2 times the foneg ((lambda)).

For example, spacing between the driven element and the director might be 0.15 (lambda).

Step 5: Simulate andd Optimize

Using elektromagnetic simulation compatiare, input the calculated dimensions and spacing. Adjuss parameters to o optimize gain and bandwidth for 5G performance.
