antenna

is called an electromagnetic wave because it is made up of both electric and magnetic fields

• Magnetic Waves

• Radio Waves

• EM Waves

• Electric Waves

is an invisible force field created by a magnet

• magnetic induction

• magnetic force

• magnetic waves

• magnetic field

an invisible force field produced by the presence of a potential difference between two conductors

• Magnetic Fields

• Electric Fields

• Radio waves Fields

• Track and Fields

a constant ratio between the electric field strength of a radiated wave to the magnetic field strength of the wave and is equal to 377 Ω

• Near Field Space

• Impedance of space

• Surge Impedance

• Nature of Space

the region directly around the antenna where the electric and magnetic fields are distinct.

• far field

• near field

• exact field

• track and field

these are not radio waves, but they contain the information transmitted

• near field

• far field

• exact field

• track and field

also referred to as “Fresnel Zone”

• near field

• far field

• field of intensity

• track and field

used in RFID and NFC

• Far Field

• Far Intensity Field

• Near Exact Field

• Near Field

approx. 10λ from the antenna is the radio wave with electric and magnetic fields

• Near Field

• Far Field

• Far Exact Field

• Near Exact Field

also called as “Fraunhoffer Zone”

• Near Field

• Far Field

• Exact Field

• Constant Field
