What is a High-gain 1800MHz Yagi Antenna?

The High-gain 1800MHz Yagi Antenna style CTRF-ANTENNA-YAGI-1800-7619-SMA antenna item is an 1800 MHz Yagi Antenna with a 13dBi High-gain directional antenna Yagi-Uda antenna manufactured by C&T RF Antennas Inc for outdoor wireless network applications.

Yagi antenna reflector and active element spacing selection

Yagi antenna reflector and active element distance between the general to 0.15-0.23 wavelength. This spacing mainly affects the front and rear field strength ratio and input impedance of the yagi antenna.

When the spacing is 0.15-0.17 wavelength, before and after the higher, but the antenna input impedance is small (about 15-20 ohms); When the spacing is 0.2-0.23 wavelength, before and after the lower, but the antenna input impedance is large (about 50-60 ohms), easy to match with the coaxial cable.

How to choose the Yagi antenna reflector length?

Yagi antenna lead length selection has two programs. One is the length of each lead, about 0.38-0.44 wavelength.

The advantage of this program is easier to process and adjust, but the frequency band is narrower. Another is that the length of each lead with the serial number increases with a long to short gradual change.

The first lead length is 0.46 wavelength, and the subsequent lead length is decreasing by a 2-3% shortening factor.
The advantage of this program is a slightly wider band, but the debugging, and processing trouble. In practice, the first scheme is used.

How to choose the Yagi antenna reflector length?

Yagi antenna reflector length is generally selected between 0.5-0.55 wavelength. Its length cannot be shorter than the design of the lowest frequency corresponding to 1/2 wavelength.

The passive element radius is determined according to the requirements of the yagi antenna passband. Usually, the radius of the element is chosen in 1/(500-80) wavelength length.

What is the active element structure and size?

The active elements can choose a single half-wave oscillator or folded oscillator, a general length of 0.475 wavelengths. The thicker the oscillator, the shorter the length should be.

What are the Gain and main flap width estimations of the Yagi antenna?

Gain ~ 10 * (antenna length)/wavelength

Main flap width ≈ 55 * square root (antenna wavelength/length)
