Web10 okt. 2014 · To feed the antenna with 50 ohm coaxial cable, a match is required to transform the antenna impedance to 50 ohms (50+j0). We measured the impedance of our 15m antenna: 53-j328 ohm. So R=53, … WebIf an inductor has a high Q factor means that the inductor behaves closely to an ideal inductor. The Q factor of an inductor is calculated by using the following formula. Where, Q = Quality factor of the inductor f = Frequency (in Hz/kHz/MHz/GHz) L = Inductance (in nH/µH/mH/H) R = Internal resistance (Ω) Get the RF Calculator App

Inductor - Wikipedia

WebAn inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil. WebAn inductor is a two-terminal passive electrical component consisting basically of an insulated wire wound around a magnetic core or without it (air core) in the form of a coil. Inductors are also called coils and chokes. uiowa research

"WebFerrite beads prevent electromagnetic interference (EMI) in two directions: from a device or to a device. A conductive cable acts as an antenna – if the device produces radio-frequency energy, this can be transmitted through the cable, which acts as an unintentional radiator.In this case the bead is required for regulatory compliance, to reduce EMI.

You can use lumped elements to increase the bandwidth of the antenna without increasing the size of the antenna. le = lumpedElement(Name,Value) returns the lumped element circuit based on the properties specified by one or more Name,Value pair arguments. lumpedElement …

WebSimilarly for the antenna side of the tuner. Suppose C2 is chosen so that it has a capacitive reactance of 100 ohms. The same thing applies between E (chosen to be 400 ohms away from G) and C so the antenna side will see an inductive reactance of 400 ohms. E and C are virtually connected. WebThe combination has an effective combined capacitance of 43 pF, requiring the same 147 µH of inductive reactance. Its characteristics are similar to those of Antennas 5 and 6. Bandwidth.
