Abstract :
An angular bandpass filter is designed. The structure is made of an array of chains of interconnected Split Ring Resonators. It may be applied for increasing directivity of antennas or reducing grating sidelobes. The main advantage over previous angular filters is the smaller thickness of the structure which is a small fraction of the wavelength while previous designs had always a thickness near one wavelength.
