A low profile radiating element with nearly hemispheric coverage for satellite communications on-the-move hybrid array antenna [PDF]
, 2010 A novel design solution of a dual-linearly polarised Ku-band low-profile radiating element for low elevation angle coverage (down to 10° above horizon) is presented. Such an element is suitable for full-duplex Satellite Communications On-The-Move (SCOTM)
