Radiation Pattern Measurements Of The Nasa Mars Science Laboratory UHF Entry Antenna Using A Spherical Near-Field Range
By Paula R. Brown, David Farr, John Demas, and Jesus A. Aguilar
Measurements of a conical micro-strip Wraparound™ antenna array mounted on a portion of the entry vehicle for NASA’s Mars Science Laboratory mission were completed at Nearfield Systems, Inc.’s new spherical near-field range facility. The Wraparound™ antenna, designed and manufactured by Haigh-Farr, Inc., provides nearly full spherical coverage and operates in the UHF frequency band for telecommunications to orbiting assets at Mars. A summary of the measurements techniques and results are presented, along with a comparison of the measured and calculated patterns.
