There are several circuits that can be used for antenna tuners, each having its own attributes. They vary from simple L configurations with an inductor and a capacitor to other types with more components.L netw
As the vehicle moves, the vertical antenna at the base station will not need to re-orientate their antenna. So too on the vehicle where it will be changing its direction, the all around radiation and reception is essential. Vertically polarised radiation: Having a vertical element, or elements...

The Variable Inclination Continuous Transverse Stub (VICTS) antenna is a unique type of antenna used in communication and navigation systems. It works by utilizing a seri
The collector is the transistor's positive lead. NPN transistors have a p-type silicon base. It's sandwiched between two layers of n-type silicon -- the emitter and collector. The emitter is moderately sized and heavily doped. Its primary function is to supply the electrons, known as the ...
The simplest type of PCB antenna is the loop antenna. Its simple closed loop of PCB board is connected with receiver or transmitter terminals. This antenna may look like a round or rectangular loop. The efficiency of this antenna depends upon the size of the loop and the copper material used...
This article talked about the RSSI level meaning, its basics, and the different units to represent it. RSSI is measured in arbitrary units and is the relative received signal intensity in a domestic wireless environment in our home and offices. After antenna and potential cable loss, RSSI shows...
GPS spoofing can also be done with commercially available, cheap, and portable equipment too, including using software-defined radios running open-source software. With this type of spoofing, a broadcast antenna is used to point at a target’s GPS receiver to override the GPS signals provided by...
An RFID tag in its most simplistic form, is comprised of two parts –an antenna for transmitting and receiving signals, and an RFID chip (or integrated circuit, IC) which stores the tag’s ID and other information. RFID tags are affixed to items in order to track them using an RFID ...
Usually, the faster a battery is used, the more its ampere hour rating declines. This gives rise toPeukert's law, which happens when batteries drain more quickly and thus have less available amperage. Frequent draining affects battery life. When batteries are rapidly discharged, they produce a ...
