### Antenna characteristic, antenna gain and directivity

Due to the special design of the antenna, the radiation density can be concentrated in a certain spatial direction. The measure of lossless antenna directivity is antenna gain. It is closely related to the directivity of the a...

### Definition/Calculation Formula/Transmitting Power of Antenna Gain

DescribeAntenna gain is a very important part of the antenna knowledge structure, and of course it is also one of the important parameters for selecting an antenna. Antenna gain also plays an important role in the operation qual...

### How to measure antenna gain?

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 principle of antenna gain, how to calculate the antenna gain?

When many people buy a wireless router, they will see such a parameter as "antenna gain". The dealer tells you that this will make the wireless signal strong...

### Optimal coverage scenarios for antennas of different specifications and gains

### What is Antenna gain ?

Antenna gain is a very important part of the antenna knowledge structure, and of course it is also one of the important parameters for selecting an antenna

### What does the relationship between antenna size and frequency?

The relationship between the size of the general designed antenna and the operating frequency of the antenna is:

Antenna length = C/(2f)

### How to realize the design of a high-gain reflectarray antenna

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. In this paper, five ra...

### The basic principle of antenna, 40 kinds of antenna introduction

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.

### Best Practices for RF Antenna Implementation and Debug

With the proliferation of wireless devices, strong signal strength and high-quality RF antenna design and integration are now required for optimal performance.

### How does the Yagi antenna achieve circular polarization?

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.
