Polarization of plane waves
Polarization is one of the basic characteristics of antennas. We first need to understand the polarization of plane waves. We can then discuss the main types of antenna polarization. linear polarization We will begin to understand the polarization o...Read more -
Understand the working principles and applications of waveguide to coaxial converters
A coaxial adapter waveguide is a device used to connect different types of waveguide transmission lines. It allows conversion between coaxial cables and waveguides for signal transmission and connection in different wireless communication systems, radar systems, microwav...Read more -
Basic knowledge of microwave coaxial lines
Coaxial cable is used to transmit RF energy from one port or component to other ports/parts of the system. Standard coaxial cable is used as microwave coaxial line. This form of wire usually has two conductors in a cylindrical shape around a common axis. They are all sep...Read more -
Introduction to RFMISO product manufacturing process—vacuum brazing

Antenna frequency
An antenna capable of transmitting or receiving electromagnetic (EM) waves. Examples of these electromagnetic waves include light from the sun, and the waves received by your cell phone. Your eyes are receiving antennas that detect electromagnetic waves at a specific fre...Read more -
The importance of antennas in the military field
In the military field, antennas are a very important technology. The purpose of an antenna is to receive and transmit radio frequency signals to enable wireless communication with other devices. In defense and military aspects, antennas play a vital role as they are used...Read more -
Antenna bandwidth
Bandwidth is another fundamental antenna parameter. Bandwidth describes the range of frequencies that the antenna can correctly radiate or receive energy. Typically, the required bandwidth is one of the parameters used to select the antenna type. For example, there are m...Read more -
Analysis of the structure, working principle and usage scenarios of microstrip antennas
Microstrip antenna is a common small-sized antenna, consisting of a metal patch, a substrate and a ground plane. Its structure is as follows: Metal patches: Metal patches are usually made of conductive materials, such as copper, aluminum,...Read more -
Antenna efficiency and antenna gain
The efficiency of an antenna is related to the power supplied to the antenna and the power radiated by the antenna. A highly efficient antenna will radiate most of the energy delivered to the antenna. An inefficient antenna absorbs most of the power lost within the anten...Read more -
Learn about planar antennas
Planar antenna is a type of antenna widely used in communication systems. It has a simple structure and is easy to make. It can be arranged on a flat medium, such as a metal plate, a printed circuit board, etc. Planar antennas are primarily made of metal and usually come...Read more -
What is antenna directivity
Directivity is a fundamental antenna parameter. This is a measure of how the radiation pattern of a directional antenna is. An antenna that radiates equally in all directions will have a directivity equal to 1. (This is equivalent to zero decibels -0 dB). The function of...Read more
