Slot Antenna Design - KB7TRZ

Abstract:

Slot antennas can be used for fixed stations, satellite ground stations and beacons. With
proper mounting, a slot antenna can also be used for ‘microwave mobile’. With a 16-slot
total, the antenna can have 10-12 dBi gain.


Slot antennas can be built from surplus waveguide sections, which will give an omni-
directional pattern and horizontal polarization. This paper offers a computer aided
method to calculate the proper dimensions for the slots and their locations.


Because the antenna is of one-piece construction, it is rugged and can be built cheaply,
requiring only access to a reasonably precise drill press or milling machine. (Note: A
precise milling machine is almost a necessity...de W3RJW)
