- Abstract
- It is shown that along with the UC-PBG lattice (Uniplanar Compact Photonic Band Gap) to create flat thin PBG structures (Photonic Band Gap) other types of bandwidth grids can be used. To study the locking bands in flat PBG structures of finite dimensions, a waveguide model is proposed in the form of a wide thin rectangular waveguide in which part of one of the wide walls is replaced by a band-pass grating. By numerical calculations of the frequency dependences of the reflection and transmission coefficients, the locking bands were determined in three PBG models, including the UC-PBG structure model. At the same time, it was shown that deep minima (–40 dB and deeper) in the microwave range are achievable at structure thicknesses of 1–2 mm or less. The possibility of providing effective isolation between transmitting and receiving microstrip antennas using a PBG structure based on an array of square slits is shown.
