Witrynaa λ/4 monopole antenna excited by a source at its base exhibits the same radiation pattern in the region above the ground, compared to a λ/2 dipole in free space. This is because, from image theory, the conducting plane can be replaced with the image of a second λ/4 monopole. However, the monopole can only radiate above the ground plane. WitrynaThe Vivaldi antenna. Below is an image of a Vivaldi antenna that we grabbed from U. S. patent 6,043,785, Broadband fixed-radius slot antenna arrangement invented by Ronald A. Marino. This figure was provided as "prior art", and provides a good picture of how the antenna works. A microstrip line (dotted) on the opposite site crosses a slot line.

WitrynaHelical Antenna. Helical antennas have two predominant radiation modes: the normal mode and the axial mode. The axial mode is used in a wide range of applications. In the normal mode, the dimensions of the helix are small compared to its wavelength. This antenna acts as the short dipole or monopole antenna.
