### Half wavelength dipole antenna

1. 1. HALF WAVELENGTH DIPOLE ANTENNA IN CONDUCTING AND DIELECTRIC MEDIUM Presented by: Pankaj kumar singh (100101ECR008) Pravakar Pradhan (100101ECR011) Amit kumar (100101ECR019)
2. 2. DIPOLE ANTENNA  A dipole antenna is a linear metallic wire or rod with a feed point at the center.  A dipole antenna has two symmetrical radiating arms.
3. 3. DIPOLE IN CONDUCTING AND DIELECTRIC MEDIUM  Dipole antenna can’t work in any conducting medium because electromagnetic waves can’t propagate through it.  Generally antenna works in free space.  For the case of any other dielectric medium some parameters will get changed due to the different values of relative permittivity and relative permeability.

5. 5. DIFFERENCE HALF WAVE DIPOLE FULL WAVE DIPOLE
6. 6. PARAMETERS We have taken operating frequency 600MHz. And calculated the followings parameters, Wavelength = 0.5m Dimension = 0.25 m Directivity = 1.643 (2.15dB) Maximum effective aperture = 0.0327m Effective length of the antenna = 0.159m

8. 8. CONCLUSION Half wavelength dipole antennas are most commonly used because the radiation resistance of half wavelength dipole antenna is 73Ω which is very closer to the 75Ω which is the characteristics impedance of some transmission lines.
