How to choose the antenna?
Aug，5 2020
How to choose the antenna? Expected to finish reading in 8 minutes Antenna Selection Guide An antenna is a device that radiates radio frequency signals from a transmission line into the air or receives it from the air onto a transmission line. It can also be regarded as an impedance converter or an energy converter, which converts the guided wave propagated on the transmission line. Tr...

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 ...

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...

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...
