How a antenna works
Web1 de out. de 2015 · As already mentioned, a small AM receiver magnetic antenna tries to maximize the number of turns to convert the incident H field to as big a signal voltage as possible but the number of turns is limited by the inter-winding capacitance so to make it tunable there is a limit to the number of turns. Lower frequencies clearly can mean more … Web12 de jun. de 2024 · Answers (1) Unfortunately, as of now you cannot model a J-pole antenna using Antenna Toolbox.

The impedance of the slot antenna ( Z S) is related to the equivalent dipole ( Z D) by: Z S Z D = η 2 4. where η is the impedance of free space, about 120πΩ. So if the impedance of a long, thin, half-wave dipole is about 72Ω, then a long, thin slot has an impedance of about: ( 120 π Ω) 2 4 ⋅ 72 Ω ...

It is shown, mathematically, how a parabolic antenna work by reflecting electromagnetic rays parallel to its axis onto the focus as a receiver. Also a feed of electromagnetic waves at the focus of a parabolic antenna will emit rays that are reflected by the susrface of the parabola in the direction parallel to its axis.
