Bibliogov Structurally Integrated Antenna Concepts For Hale Uavs by Et Al.
This Technical Memorandum Describes Work Done In Support Of The Multifunctional Structures And Materials Team Under The Vehicle Systems Program'S Itas (Integrated Tailored Aero Structures) Project During Fy 2005. The Electromagnetics And Sensors Branch (Esb) Developed Three Ultra Lightweight Antenna Concepts Compatible With Hale Uavs (High Altitude Long Endurance Unmanned Aerial Vehicles). Esb Also Developed Antenna Elements That Minimize The Interaction Between Elements And The Vehicle To Minimize The Impact Of Wing Flexure On The Em (Electromagnetic) Performance Of The Integrated Array. In Addition, Computer Models Were Developed To Perform Phase Correction For Antenna Arrays Whose Elements Are Moving Relative To Each Other Due To Wing Deformations Expected In Hale Vehicle Concepts. Development Of Lightweight, Conformal Or Structurally Integrated Antenna Elements And Compensating For The Impact Of A Lightweight, Flexible Structure On A Large Antenna Array Are Important Steps In The Realization Of Hale Uavs For Microwave Applications Such As Passive Remote Sensing And Communications.
