ABSTRACT:
An improved microwave absorber for coupling and absorbing radio frequency energy used for communication, navigation and radar systems. The structure has a conformal energy receiving surface for receipt on reflecting surfaces or surfaces supporting unwanted surface waves. The microwave absorber provides an effective means for antenna radiation pattern control, reduction of antenna to antenna coupling caused by reflections or surface waves and improved low angle response with a minimal effect on high angle of incidence performance.
