Antenna gain refers to the ratio of the power density of the signal generated by the actual antenna and the ideal radiating unit at the same point in space under the condition of equal input power. It quantitatively describes the degree to which an antenna concentrates the input power and radiates it.
The relationship between the size of the general designed antenna and the operating frequency of the antenna is:
Antenna length = C/(2f)
A simple and convenient method of making a radio antenna, the effect is very good, and it is now posted to share with everyone.
Reflectors are widely used to change the lobe pattern of an antenna. Using a sufficiently large flat reflector can eliminate the back radiation of the antenna and significantly increase the antenna gain
The evaluation and production methods of the flat-panel booster antenna are complete. It seems that the finished antenna still has advantages.
Antennas are an essential part of wireless transmission. Except that we use optical fibers, cables, network cables, etc. to transmit wired signals, as long as the signals are transmitted by electromagnetic waves in the air, various forms of antennas are required.
With the proliferation of wireless devices, strong signal strength and high-quality RF antenna design and integration are now required for optimal performance.
The polarization of the antenna is an important theory of the antenna, which mainly refers to the direction of the electric field strength formed when the antenna radiates.
This article will mainly focus on circularly polarized antennas.
What is the difference between a circularly polarized antenna and a linearly polarized antenna?
dBi, dB, dBm, dBd, dBc, they all look similar, but the difference inside is still obvious.
