Since the antenna material is a flexible metal similar to the tape of a roller meter, the chosen geometry allows to wrap the monopole around pivot placed on the CubeSat face and turn down the helix on the same face during the launch phase. /ca 1 >> The Genesat-1 technology demonstration mission validated the use of research quality instrumentation for in situ biological research and processing. /CropBox [0 0 595.22 842] 'Certified by IEEE PDFeXpress at 09/20/2016 1:23:39 AM' /Contents 48 0 R The overall ground plane size is 100 mm × 100 mm × 0.5 mm. After its launch from Wallops Flight Facility as a secondary payload off a Minotaur launch vehicle on December 16, 2006, all primary science and engineering test objectives were completed successfully within one month of operation. This antenna is proposed for deployment on a CubeSat platform, where the new feeding technique allows for easier antenna deployment. For CubeSats that use a dipole, these devices extend far beyond the CubeSat physical structure and require the engineers to fold the antenna into the satellite in order to meet requirements2. during the launch phase optimizing the space occupation . One of the square faces of the nanosatellite structure works as the ground plane for the slotted radiating element. endobj endobj >> UHF Antenna is circularly polarized for secure reception. /SMask 67 0 R A square ground plane with slotted rectangular radiating element have been used. /BM /Normal Both antennas display logarithmic periodicity in their structure. The problem with a patch antenna is that it can only radiate from one side, and removes space for a solar cell. 2017-09-06T06:16:05-07:00 If your cubesat is using a commercial RF system that has been designed to work with a pair of crossed dipoles, then it may have circuits which sense the state of the polarization and combine the two antennas correctly; it will "look" right hand or left hand polarized or linearly polarized to the cubesat depending on the specific 3D orientation (attitude) of the cube sat at each moment. The simulated farfield radiation patterns at the frequency, pattern with a maximum in the xy plane for the z-directed m. the yz-plane for the y-directed monopole.
