PBG filter

I want to design a PBG microstrip filter passband is 820MHz-960MHz and the stopband is 1.71GHz-2.17GHz.

Anyone can share the design experience with me.

Thanks!

limited observations

Since no one with direct experience has responded, I will give you my observations. It looks like these designs are done by pretty much trial and error with E&M simulators. It looks like they are setting up periodic structures which have Brillouin zones. You can read "Wave Propagation in Periodic Structures" by Leon Brillouin which was published in 1946 and reprinted by Dover in 1953. This book contains the theory as applied to crystal structures and transmission lines. The book does not specifically address the modern microstrip designs, but it will give you the point of view to take in thinking about them.

In my opinion, I suggest you to use a 3D e.m. software like CST Mws and HFSS. Do you think to insert periodic holes into the ground plane or
into the dielectric?
Do you have experience on PBG antennas?
