The principle of antenna gain, how to calculate antenna gain
Antenna gain refers to the radiated power gain of an antenna in a specific direction relative to an ideal point source antenna. It represents the radiation capability of the antenna in a specific direction, that is, the signal reception or emission efficiency of the ante...Read more -
Four basic feeding methods of microstrip antennas
The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator and a ground plate. The thickness of the dielectric substrate is much smaller than the wavelength. The thin metal layer on the bottom of the substrate is connected to the groun...Read more -
Antenna Polarization: What is Antenna Polarization and Why It’s Important
Electronic engineers know that antennas send and receive signals in the form of waves of electromagnetic (EM) energy described by Maxwell's equations. As with many topics, these equations, and the propagation, properties of electromagnetism, can be studied at different l...Read more -
The working principle and application of horn antenna
The history of horn antennas dates back to 1897, when radio researcher Jagadish Chandra Bose conducted pioneering experimental designs using microwaves. Later, GC Southworth and Wilmer Barrow invented the structure of the modern horn antenna in 1938 respectively. Since t...Read more -
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 -
