Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). 38 questions in Slot Antenna | Science topic - ResearchGate As the resonant slot antenna elements are radiating the part of the power excited the slot aperture, the input power supplied to the waveguide may not be able to travel a long distance in the ...
