摘要：

In low-profile applications, ground plane backing significantly degrades antenna performance when the electrical height is a small traction of a wavelength. An approach to suppress the destructive interference from the ground plane reflections is to employ absorbing layers of ferrite materials. lit this paper, we introduce it means to also control and utilize the mode excited in these finite ferrite layers to recover antenna performance at ultra/very high frequencies. Experimental verification Is provided using commercial ferrite materials.
