Sähköantennityyppejä
Sähköantennityyppejä refers to the various designs and configurations of electrical antennas used for transmitting or receiving electromagnetic waves. These antennas convert electrical signals into radio waves or vice versa. The choice of antenna type depends on factors such as the desired frequency range, radiation pattern, bandwidth, and physical constraints.
Common types include dipole antennas, which are simple, linear conductors. Monopole antennas are another basic type,
For directional applications, parabolic dish antennas focus electromagnetic waves to a single point, offering high gain
More specialized types include patch antennas, which are flat, metallic patterns on a dielectric substrate, often
