Abstract :
The gridded corner-reflector antenna consists of two lines of metal rods which meet at an angle to form a corner. It is fed by a dipole and is used in situations where a moderate gain is required from a simple antenna, particularly at UHF and low microwave frequencies. This paper uses FDTD to predict the radiation characteristics and shows how the spacing of the rods in the grid influences the gain and front-to-back ratio.
