What is a horn antenna? What are the main principles and uses?
Horn antenna is a surface antenna, a microwave antenna with a circular or rectangular cross-section in which the terminal of the waveguide gradually opens. It is the most widely used type of microwave antenna. Its radiation field is determined by the mouth size and propa...Read more -
Do you know the difference between soft waveguides and hard waveguides?
Soft waveguide is a transmission line that serves as a buffer between microwave equipment and feeders. The inner wall of the soft waveguide has a corrugated structure, which is very flexible and can withstand complex bending, stretching and compression. Therefore, it is ...Read more -
Commonly used antennas | Introduction to six different types of horn antennas
Horn antenna is one of the widely used antennas with simple structure, wide frequency range, large power capacity and high gain. Horn antennas are often used as feed antennas in large-scale radio astronomy, satellite tracking, and communication antennas. In addition to s...Read more -

Energy conversion in radar antennas
In microwave circuits or systems, the entire circuit or system is often composed of many basic microwave devices such as filters, couplers, power dividers, etc. It is hoped that through these devices, it is possible to efficiently transmit signal power from one point to ...Read more -
Waveguide matching
How to achieve impedance matching of waveguides? From the transmission line theory in microstrip antenna theory, we know that appropriate series or parallel transmission lines can be selected to achieve impedance matching between transmission lines or between transmissio...Read more -
Trihedral Corner Reflector: Improved Reflection and Transmission of Communication Signals
A trihedral reflector, also known as a corner reflector or triangular reflector, is a passively target device commonly used in antennas and radar systems. It consists of three planar reflectors forming a closed triangular structure. When an electromagnetic wave hits a tr...Read more -
Effective aperture of antenna
A useful parameter calculating the receive power of an antenna is the effective area or effective aperture. Assume that a plane wave with the same polarization as the receive antenna is incident upon the antenna. Further assume that the wave is travelling towards the ant...Read more -
Slotted Waveguide Antennas – Design Principles
Figure 1 shows a common slotted waveguide diagram, which has a long and narrow waveguide structure with a slot in the middle. This slot can be used to transmit electromagnetic waves. figure 1. Geometry of the most common slotted wavegu...Read more
