Antennas can be classified into several types based on various factors such as frequency, design, application, etc. Here are some of the most common types of antennas:

1. Dipole Antennas: These are the simplest type of antenna, consisting of a metal rod or wire split into two pieces and fed by a transmission line at the center.

2. Monopole Antennas: These are a type of dipole antenna, but with only one-half of the dipole, making them smaller in size. They are often mounted over some type of ground plane.

3. Loop Antennas: These antennas have a loop of wire, often fed by a transmission line. They can be small or large, and are often used for receiving and transmitting at low frequencies.

4. Array Antennas: These are a group of antennas working together to achieve more directional radiation patterns. They can provide increased gain compared to a single antenna and can be used to form beams that can be steered.

5. Yagi-Uda Antennas: These are directional antennas consisting of a driven element, a reflector, and one or more directors. They are often used for communications at higher frequencies.

6. Parabolic Antennas: These antennas use a parabolic reflector to direct the radio waves. They are used for high-gain applications such as satellite communication and radio astronomy.

7. Horn Antennas: These are used for transmitting and receiving radio waves over a range of frequencies, often used in microwave applications.

8. Patch Antennas: These are a type of microstrip antenna that are widely used in mobile and wireless applications due to their low profile and ease of fabrication.

9. Log-Periodic Antennas: These antennas provide a wide bandwidth and are often used for television reception and shortwave radio.

10. Helical Antennas: These are a type of directional antenna with a helix-shaped wire, often used for satellite communication.

Each type of antenna has its own advantages and disadvantages, and the choice of antenna depends on the specific requirements of the application.
