Radar antenna2
Main lobe width For any antenna, in most cases, its surface or surface direction pattern is generally petal shape, so the direction pattern is also called lobe pattern. The lobe with the maximum radiation direction is called the main lobe, and the rest is called the side lobe. The lobe width is f...Read more -
Radar antenna
In 1873, British mathematician Maxwell summed up the equation of electromagnetic field – Maxwell equation. The equation shows that: electric charge can produce electric field, current can produce magnetic field, and the changing electric field can also produce magnetic field, and the changi...Read more -

How important is the external antenna
The antenna is a very important part of the radio system and its importance cannot be overstated. Of course, antennas are only one aspect of a radio system. When discussing antenna, people often talk about height and power. In fact, as a system, all aspects should be reasonably planned and arrang...Read more -
Comparison of advantages and disadvantages of PCB antenna, FPC antenna and LDS antenna
Compared with the external antenna, PCB antenna, FPC antenna, LDS antenna and other internal antennas have their own unique product form. These three can not be regarded as differences, each has its own advantages and applications. 一，PCB Antenna Cellular /WiFi multi-band embedded flexible PCB a...Read more -
The internal antenna must have a weaker signal than the external antenna?
At present, most routers on the market adopt the design of external antenna, from 1 antenna at the beginning to 8 antennas or even more, and with the development of technology, hidden antenna is gradually popular, and wireless routers gradually “remove” the antenna. However, many user...Read more -
Base Station Antenna Industry Analysis
5ghz omni antenna 1.1 Definition of Base Station Antenna The base station antenna is a transceiver that converts the guided waves propagating on the line and the space radiated electromagnetic waves. It is built on the base station. Its function is to transmit electromagnetic wave signals o...Read more -

Precautions for using GPS locator
Precautions for using GPS locator 1. GPS can not be 100% positioning, let alone believe the nonsense of indoor positioning – GPS is not like mobile phone broadcast, you can receive signals anywhere, many things will affect GPS reception, including sky star distribution status, buildings, ...Read more -
GPS antenna performance
GPS antenna performance We know that a GPS locator is a terminal for positioning or navigation by receiving satellite signals. In the process of receiving signals, an antenna must be used, so we call the antenna that receives the signal a GPS antenna. GPS satellite signals are divided into L1 an...Read more
