Low Earth Orbit (LEO) satellite technology has become the core of the development of the global communications industry and space technology. Its characteristics of low latency and high coverage can not only make up for the shortcomings of ground communications, but the LEO industry is also facing explosive challenges behind its booming development. Let’s start with the…
1. What is antenna? The basic function of an antenna is energy conversion, which converts the electrical signal transmitted from the wire (feeder) into radio waves and transmits them into space. The mechanism of antenna radiation of electromagnetic waves is derived from Maxwell’s equations. Electric charges can generate electric fields, and currents can generate magnetic…
Satellite communication is a wireless communication method that uses satellites as the communication medium. In previous articles, we introduced satellite communication systems of parabolic antennas in detail, mainly analyzing parabolic antennas. Today we are going to introduce another type – phased array antennas. Antesky Earth Station Antenna Projects of parabolic antennas Phased array antenna is a type…
As we all know that the 5G network of mobile communications has been officially launched, and the frequency used by 5G base stations is close to the C band of satellite communications, which will interfere with the downlink frequency band of satellite earth stations and seriously threaten the normal reception of satellite broadcasting and…
Power amplifier (PA) or up-converter power amplifier BUC (Block Up-Converter) is a device used in wireless communication, radar, and satellite communication. Its main function is to effectively convert weak signals into strong output signals by increasing the power of the signal so that it can be effectively transmitted through the antenna. The L-band signal output…
An emergency communication satellite antenna like FlyAway Satellite Antennas antenna, satellite antenna dish is a critical component used to establish and maintain reliable communication during emergencies or crises. These FlyAway Satellite Antennas are designed to be robust, easy to deploy, and capable of performing well under challenging conditions. Here’s an overview of the key aspects related to emergency communication satellite antennas: Types of…
From August 14th to August 16th, our factory hosted a client visit focused on an in-depth examination of our 7.3 meter C band Rx only antenna and series 8000 Antenna Control System. During the three-day visit, the client immersed themselves learning how to install and maintain antenna and conducted thorough tests on the antenna and series 8000 ACS. Key evaluations included…
Feed is an important component used in wireless communication systems, and it plays a key role in wireless transmission. This article will introduce the basic concepts, working principles, and design details of the x-band feed. The x-band feed refers to a feed device that works in the x-band frequency range. The x-band is an important frequency…
Previously, we introduced the basic theory of satellite antenna dish types in detail, which mentioned the concept of antenna polarization. Regarding the polarization of electromagnetic waves, we described it in detail in the article ” The Polarization of Antesky 4.5m Satellite Dish” and compiled some vivid pictures to illustrate it. In practical applications, electromagnetic waves are emitted by…
