A L-band multiple-beam phased array antenna with integrated structural design for satellite usage is described in this paper. By using the integrated design, the height of the filters and the LNA modules are reduced, and all the radiating elements and modules are assembled on one integral panel. Meanwhile, a solder-less junction structure is developed between the radiating elements and the filters...
A probe-fed stacked U-slot patch antenna for satellite applications is presented. The impedance bandwidth (VSWR≤1.5) of 7.7% is achieved at the designed frequency fo. The simulated peak realized gain of the proposed antenna is about 9 dBi.
In this paper, a high-precision digital phase-shifting and attenuating module for satellite phased array antenna is introduced. With hybrid integration of the beam lead PIN diodes, the RT/Duroid 5880 laminates, the packaged driving devices, the module achieves high-precision phase-shifting and attenuating characteristics, small insertion loss, high linearity and good flatness of amplitude and phase,...
An optimization approach based on alternating projection (AP) is proposed to generate low earth orbit (LEO)-satellite-borne multiple patterns with isoflux coverage. The purpose is to find a common amplitude distribution and different phases corresponding to the different patterns. The common amplitudes are with finite levels, which are calculated adaptively in the iteration. To demonstrate the good...
