Abstract :
This paper presents results for an array of patch embedded in an EBG. The EBG surface is composed by short-circuited microstrips densely coupled each other through interlocked branch stubs. With respect to a conventional mushroom surface, this structure exhibits a better space-wave decoupling performance. The experimental results demonstrate decoupling till 38 dB in both planes for patches separated by only one half free-space wavelength.
