Flashcards
Antenna Polarization Types
Antenna Polarization Types
Oblique polarization is not a standard type of antenna polarization. Common types include vertical, horizontal, and circular.
Parabolic Reflector Function
Parabolic Reflector Function
A parabolic reflector focuses the signal into a narrow beam, enhancing the antenna's ability to send or receive signals in a specific direction.
Frequency vs. Antenna Size
Frequency vs. Antenna Size
As frequency increases, the required antenna size decreases. This is because the wavelength is inversely proportional to the frequency.
