Antenna Theory – Types of Antennas
Antennas have to be classified to understand their physical structure and functionality more clearly. There are many types of antennas depending upon the applications applications.
| Type of antenna | Examples | Applications |
|---|---|---|
| Wire Antennas | Dipole antenna, Monopole antenna, Helix antenna, Loop antenna | Personal applications, buildings, ships, automobiles, space crafts |
| Aperture Antennas | Waveguide (opening), Horn antenna | Flush-mounted applications, air-craft, space craft |
| Reflector Antennas | Parabolic reflectors, Corner reflectors | Microwave communication, satellite tracking, radio astronomy |
| Lens Antennas | Convex-plane, Concave-plane, Convex-convex, Concaveconcave lenses | Used for very highfrequency applications |
| Micro strip Antennas | Circular-shaped, Rectangularshaped metallic patch above the ground plane | Air-craft, space-craft, satellites, missiles, cars, mobile phones etc. |
| Array Antennas | Yagi-Uda antenna, Micro strip patch array, Aperture array, Slotted wave guide array | Used for very high gain applications, mostly when needs to control the radiation pattern |
Let us discuss the above-mentioned types of antennas in detail, in the coming chapters.
