Calculation of antenna gain
Mar，25 2020
Calculation of antenna gain Expected to finish reading in 10 minutes Gain refers to the ratio of the power density of the signal generated by the actual antenna and the ideal radiating unit at the same point in space under the condition of equal input power. It quantitatively describes the degree to which an antenna concentrates input power to radiate. The gain is obviously closely related to the ...

Uncovering large scale MIMO technology: key factor of 5g super high speed rate
Mar，13 2020
Uncovering large scale MIMO technology: key factor of5gsuper high speed rate Expected to finish reading in 5 minutes In5gera, even if the signal is only one or two boxes, we can download files, video chat or watch online movies without any scruple. In most cases, these are as smooth as listening to music online. 5g large-scale MIMO (multiple input and multiple output) technology is one of the keys...

Lora system of intelligent well cover
Nov，15 2019
Lora system of intelligent well cover There is a popular saying about Urban Governance: sewer is the conscience of a city. In the city, there are all kinds of densely distributed pipe networks underground, which are used for sewage discharge, drainage, various pipeline laying, etc. In these pipe networks, a node is the well cover we can see, walking in the road, sidewalk, park, community, f...

From a professional point of view, what is the reason why 5G is faster than 4G network?
Oct，1 2019
From a professional point of view, what is the reason why5Gis faster than4Gnetwork? In fact, it is not "5Gis faster than4G", but "5Gis proposed to be faster than4G". Every generation of wireless communication after3Gwill put forward the target first, and then consider the system design and technology selection. Millimeter Wave (Upgraded Bandwidth) Advanced Beam Shaping (Enhanced Signal-to-Noise Ra...

Does the longer the antenna length
Sep，10 2019
Does the longer the antenna length, the better the signal it receives? Don't take it for granted, because the theory and practice prove that this statement is unscientific, and the optimal length of the antenna is actually one fourth of the wavelength. The length of the antenna is determined by the frequency of the transmitted and received signals, that is, the wavelength. When the length of the a...

What are Applications of antenna
Jul，26 2019
Everyone has seen many kinds of antennas, but why choose such antennas and why design them in this shape, do you know? Rod/whip antenna The rod/whip antenna is generally omnidirectional, i.e. it radiates uniformly at 360 degrees on the horizontal pattern, i.e. it has no directionality and generally has little gain. Such antenna applications are very common, and there are not many special requireme...

The fiberglass omni antenna application
Jul，15 2019
The use of Fiberglass radome antenna is becoming more and more extensive with the extensive application in the fields of sea, land, air and civil aviation. If the antenna is compared to the "eye" goggles on the "eye" line of the day, Fiberglass radome has a wide range of uses. The radome mainly plays a protective role. The main purpose is to protect the antenna or the whole system from the impact ...
