Abstract :
The use of a centre-feed position (instead of the more conventional end-feed) was investigated to improve the reflection coefficient bandwidth of a slotted waveguide array. The results demonstrated improved bandwidth performance, but at the cost of a degradation in the pattern and a more difficult design procedure
