“…The use of phased array antennas for reception and tracking of satellite signals has been investigated in for example [6], [7] and [8]. Much of the existing work is based on techniques other than the blind beamforming method applied in this paper.…”

Abstract-A system that uses adaptive beamforming techniques for mobile Digital Video Broadcasting Satellite (DVB-S) reception is proposed in this paper. The purpose is to enable DVB-S reception in moving vehicles. Phased arrays are able to electronically track the desired signal during dynamic behaviour of the vehicle the array is mounted on.The proposed system uses blind beamforming to adapt the array steering vector to changing signal (conditions and) directions. Movement of the vehicle, the phased array is mounted on, leads to modulus and phase deviations at the beamformer output. An extended version of the Constant Modulus Algorithm (CMA) algorithm is used to adapt the steering vector weights to compensate for those deviations.For simulation of the proposed system a model of vehicle dynamics is used to generate realistic antenna data. Simulation of the proposed system based on this antenna data shows appropriate corrections for modulus and phase deviations.

“…Several types of PAAs have been developed for land mobile satellite communication terminals. Figures 15 and 16 show two types of L-band 19-element PAAs for land mobile use, respectively [32,33]. The first one shown in Figure 15 consists of 19 orthogonal two-point-probe-fed circular patch antenna elements with parasitic elements, 18 3-bit phase shifters and a 19:1 power divider.…”

“…On the other hand, The other one shown in Figure 16 uses slot-coupled microstrip patch antenna elements and this slot coupled patch and the parasitic element are fabricated by very thin film PET substrate (εr=3.2) considering simple configuration and cost reduction. Also, this antenna uses a simple configuration of BFN using a lot of 3dB dividers and 3-bit phase shifters with frequency dependent delay characteristics in order to avoid the beam tilt between transmit and receive frequencies [33]. Conformal array antennas have also been researched for the mobile satellite communications in order to obtain wide angle coverage area.…”
