We present the design of a microstrip patch element with both frequency agility and polarization diversity over a wide frequency range. Conceptual verifications with hardware implementation using surface-mount lumped components was performed, and good agreement between measurements with simulations are presented. A measured frequency tuning ratio of 1.8:1 is presented for the circular polarization...
Very little data exists regarding the long-term aging performance of space-rated oscillators in the non-operating mode. This paper provides empirical evidence that may be used to estimate the performance of unpowered oscillators for long-term space missions, as well as an aid in validating the worst-case analyses that are routinely performed on these oscillators. The proper operation of any space...
The presented data will provide empirical evidence that may be used to estimate the performance of backup, unpowered oscillators for long term space missions, as well as an aid in validating the worst case analyses that are routinely performed on these oscillators. An essential component of any space vehicle is the onboard master oscillator and the proper operation of the entire payload is dependent...
