Antenna Introduction and Classification
1. Introduction to Antennas An antenna is a transition structure between free space and a transmission line, as shown in Figure 1. The transmission line can be in the form of a coaxial line or a hollow tube (waveguide), which is used to transmit electromagnetic energy fr...Read more -
Basic parameters of antennas – antenna efficiency and gain
The efficiency of an antenna refers to the ability of the antenna to convert input electrical energy into radiated energy. In wireless communications, antenna efficiency has an important impact on signal transmission quality and power consumption. The efficiency of the a...Read more -
What is Beamforming?
In the field of array antennas, beamforming, also known as spatial filtering, is a signal processing technique used to transmit and receive wireless radio waves or sound waves in a directional manner. Beamforming is comm...Read more -
Detailed explanation of trihedral corner reflector
A type of passive radar target or reflector used in many applications such as radar systems, measurement, and communications is called a triangular reflector. The ability to reflect electromagnetic waves (such as radio waves or radar signals) directly back to the source,...Read more -

Application of RFMISO vacuum brazing technology
The brazing method in a vacuum furnace is a new type of brazing technology that is performed under vacuum conditions without adding flux. Since the brazing process is carried out in a vacuum environment, the harmful effects of air on the workpiece can be effectively elim...Read more -
Waveguide to coaxial converter application introduction
In the field of radio frequency and microwave signal transmission, in addition to the transmission of wireless signals that do not require transmission lines, most scenarios still require the use of transmission lines for...Read more -
How to determine left-handed and right-handed circularly polarized antennas
In the antenna world, there is such a law. When a vertically polarized antenna transmits, it can only be received by a vertically polarized antenna; when a horizontally polarized antenna transmits, it can only be received by a horizontally polarized antenna; when a right...Read more -
How does a microstrip antenna work? What is the difference between a microstrip antenna and a patch antenna?
Microstrip antenna is a new type of microwave antenna that uses conductive strips printed on a dielectric substrate as the antenna radiating unit. Microstrip antennas have been widely used in modern communication systems due to their small size, light weight, low profile...Read more -
