Abstract :
An expression for the directivity of a short backfire antenna has been derived in terms of the reflection coefficient of the plane conductor. The analysis considers only the series of images behind the surface-wave reflector and the dipole feed. Using this expression, the directivity is calculated and compared with the experimentally obtained directivity. The gain was measured in the laboratory by the standard method, using microwave-absorbing material to reduce the effect of unwanted reflections from the floor, ceiling etc.
