How to do a Yagi antenna passive element size selection?

Yagi antenna passive element size selection should be mainly from the directional and impedance characteristics of two aspects to consider.

The choice of the leading element spacing. As the gain is mainly determined by L/λ, if the number of the leading vibrators has been determined, the spacing is more favorable to obtain some large, but when > 0.4λ, the antenna gain but rapidly declining, so generally takes (0.15 ~ 0.4) λ.

The first lead and active element spacing should be slightly smaller than the other element spacing, for example, ≈ 0.1λ, gain slightly improved.

Usually, the length of the guide is in the range of ≈(0.42-0.46)λ. The more the number of oscillators, the shorter the optimal length of the lead-in; if the working band is wider, the length of the lead-in should also be shorter.

Yagi antenna reflector and active element spacing are usually in the (0.15 ~ 0.23) λ range, the spacing of the direction of the map of the front and rear radiation ratio and input impedance influence, the spacing is small can effectively suppress the backward radiation, but the input impedance is low and feed line impedance matching, and thus to compromise the choice.

Reflector length is usually (0.50 ~ 0.55) λ. If the front-to-back ratio requirements are higher, the form of transmitting network can be used.

Yagi antenna passive element is generally made of an aluminum tube, conductor radius is usually selected in the range of (1/200 ~ 1/300) λ.

The oscillator thickness has no great influence on the directionality, and the impedance characteristics have some influence, the thicker the oscillator, the lower the characteristic impedance, and the wider the impedance bandwidth is favorable.

Yagi antenna guide antenna has a uniform structure and uneven structure of two forms, the former is the guide is the case of equal length and spacing, and the latter is the guide is not equal length and spacing, the farther away from the active oscillator guide, the shorter the length, the greater the spacing. They can both be adjusted to their respective best state.

In the two comparisons, generally speaking, the uniform structure of the main flap is narrower, the level of the flap is higher, and the uneven structure of the main flap is wider, the level of the flap is lower, but if the appropriate adjustment, can also be made to obviously depress the flap and not too much to expand the main flap or reduce the antenna gain.

Relatively speaking, the latter is mobile and flexible.
