Radiation Pattern Measurements Of The Nasa Mars Science Laboratory UHF Entry Antenna Using A Spherical Near-Field Range

2013-08-29 12:43:47| rfglobalnet News Articles

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. By Paula R. Brown, David Farr, John Demas, and Jesus A. Aguilar

NXP Makes UHF PCB Antenna Design As Easy As 1, 2, 3

2013-08-20 07:37:47| wirelessdesignonline News Articles

Electronic equipment manufacturers wanting to embed RFID technology in their products are now able to do so without needing deep UHF antenna design experience thanks to NXP Semiconductors’ new online software tool. The RFID – PCB Antenna Designer tool helps implement antennas on a printed circuit board (PCB) in the UHF frequency range (840-960 MHz).
