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 -
