Different Types of Antenna Used In Mobile Communication
1. Monopole Antenna:
- A monopole antenna is a single vertical rod or wire mounted on a ground plane.
- It is omnidirectional, meaning it transmits and receives signals in all directions perpendicular to the antenna’s axis.
- Monopole antennas are commonly used in mobile devices due to their simplicity and effectiveness.
2. Dipole Antenna:
- A dipole antenna consists of two conductive elements, often rods or wires, positioned in a line and fed at their center.
- It is also omnidirectional and is commonly used in base stations and some mobile devices.
3. Patch Antenna:
- A patch antenna is a flat, rectangular antenna commonly used in mobile devices.
- It consists of a metal patch on a dielectric substrate, often mounted on a ground plane.
- Patch antennas are directional and have a relatively narrow beamwidth.
4. Helical Antenna:
- A helical antenna is a coil-shaped antenna that can be either linear or circularly polarized.
- It is compact and often used in mobile devices where space is limited.
- Helical antennas are directional and have a moderate beamwidth.
5. Yagi-Uda Antenna:
- A Yagi-Uda antenna, commonly known as a Yagi antenna, consists of multiple dipole elements arranged in a line along with a single driven element and one or more passive elements (reflector and directors).
- It is highly directional and offers high gain, making it suitable for point-to-point communication.
6. Parabolic Reflector Antenna:
- A parabolic reflector antenna consists of a curved dish-shaped reflector with a feed antenna positioned at its focal point.
- It is highly directional and offers high gain, making it suitable for long-range communication links such as satellite communication and point-to-point microwave links.
