Electromagnetic anechoic chambers are frequently used to experimentally determine the radiation characteristics of antennas. In order to perform measurements of an antenna under test (AUT), a second antenna is required which must have a sufficiently broad beamwidth to evenly illuminate the AUT, and must operate over as wide a range of frequencies as possible. One such example is the omnidirectional bicone antenna (which can be engineered to have a wide bandwidth) although an antenna with a somewhat narrower beamwidth would be more practical. The best antenna for this application is likely to involve some sort of horn structure.
The aims of this project are to (i) identify appropriate structures for a wideband horn antenna (ii) design and model one or more candidate examples of these (using CST Microwave Studio); and (iii) fabricate and measure the perfomance of these.
A design of one or more wideband horn antennas.
