This metric indicates the amount of power that is reflected back to the source. Ideally, all power from the transmitter would travel up to the antenna and be emitted as radio waves. However, in reality, each antenna has a specific tuning, some of the energy will get reflected back. When ...
Internal TV antennas might be a simple set top antenna. These antennas tend to be relatively smal and by their very nature they do not have much gain, although some have an internal pre-amplifier to make up for the lower strength signals that are received. However the amplifier can fully ...
Since smart meters are typically installed outside, you will be far away from the radiation, and there are walls between you and the smart meter antenna that help reduce your exposure to RF energy even further. As such, the amount of radiation you are exposed to from a smart meter is ...
AN2972 Application note How to design an antenna for dynamic NFC tags Introduction The dynamic NFC (near field communication) tag devices manufactured by ST feature an EEPROM that can be accessed either through a low-power I2C interface or an RF contactless interface operating at 13.56 MHz. ...
The material I chose to build the j-pole antenna was 3/4 inch copper pipe used for plumbing. Here are the plans to build a 2 meter J-pole antenna: The above dimensions for the J-pole are in inches. Measurements on overall length, and stub length are from the centerline of the separa...
Traveling-wave.Adirectional antennain which the EM waves travel through the antenna in one direction, unlike many other types of antennas in which the waves travel in multiple directions. The unidirectional waves make it possible to support a wider range of frequencies. Traveling-wave antennas are...
If that isn’t an option, make the most of the speed and data you have by not streaming video. Rent DVDs, get a TV antenna, or install satellite TV for your household entertainment instead. Streaming uses a lot of data, and once your data is gone, your satellite internet speeds will ...
Comparing your network with nearby ones helps you make effective decisions toboost signal strengthand reduce interference, ensuring a more stable and reliable connection. If you just need to measure your wireless network signal strength in one location, then Inspector Mode is all you need. However,...
5G mid- and high-band spectrum introduces new, wider bandwidth capabilities for mobile networks. 5G multi-antenna solutions can also unlock higher capacity on any given bandwidth without the addition of new radio sites. Efficient coverage 5G carrier aggregation and spectrum sharing make it possible ...
It is even possible to make a television screen out of thousands of ordinary 60-watt light bulbs! You may have seen something like this at an outdoor event like a football game. Let's start with the CRT, however. The terms anode and cathode are used in electronics as synonyms for ...
