An original and flexible pyramidal antenna for satellite or terrestrial application services is presented. The ground plane of the antenna is perforated and loaded with a cutoff open-ended waveguide: this original configuration leads to a good tradeoff between rear radiation and impedance matching. Trap-loads are used to achieve multiband operation while(More)
Developing computationally efficient processing techniques for massive volumes of hyperspectral data is critical for space-based Earth science and planetary exploration (see for example, (Plaza & Chang, 2008), (Henderson & Lewis, 1998) and the references therein). With the availability of remotely sensed data from different sensors of various platforms with(More)
A novel reconfigurable and circularly polarized antenna topology for satellite application services, based on a pyramidal geometry, is proposed. Frequency agility is simply obtained by loading the radiating elements by Radio-Frequency switches. The ground plane of the antenna is perforated and loaded by a cut-off and open-ended waveguide. The length of this(More)
A new pyramidal antenna for satellite application is presented. Sierpinski triangle antennas are chosen as radiating elements for their multiband features. The ground plane of the antenna is perforated and loaded with a cutoff open-ended waveguide: this original configuration leads to a good tradeoff between rear radiation and impedance matching.
