Demonstration of two-way Extremely High Frequency (EHF) satellite communication (SATCOM) using submarine-survivable phased arrays

open access: yesMILCOM 2008 - 2008 IEEE Military Communications Conference, 2008
U.S. submarines are faced with the challenging dilemma of addressing the need for higher data rate satellite communications (SATCOM) without significantly increasing the size of the SATCOM antenna. The planar form factor of phased array technology, along with the ability to steer beams electronically, has led to submarine antenna concepts that can ...
