Abstract :
Electromagnetic band-gap (EBG) structures have been used to realize highly directive antennas either by using them as substrates and utilizing defect resonances or as a host medium when operating near band edge frequencies. As an alternative, it was recently proposed that degenerate band edge (DBE) crystals can achieve the required resonances using fewer number of unit cells, resulting in low profile structures.
