Abstract :
We present a small electromagnetic bandgap (EBG) cell which is easy to fabricate on standard PCB material and can be used where space is a premium. The EBG structure is an extension of the classical uni-planar structure where the inductance due to the thin transmission line sections is increased by meandering in these microstrip lines within the EBG cell itself. We demonstrate the concept with an EBG surface that was designed and developed at 300 MHz on standard FR4. The size of a 3 times 3 structure is only 7.53 cm times 7.53 cm and provides 10 dB attenuation across the surface
