These antennas should be able to generate multiple simultaneous beams in order to guarantee the link with different satellites. Existing gateway antennas are mainly based on reflectors dishes repointable mechanically, and able to track a single satellite instantaneously. Multibeam gateway antennas based onactive phased arrays are also under development. They can generate multiple simultaneous beams, but they are not competitive yet interms of complexity, power dissipation, thermal issues, cost. For these reasons, in this activity innovative multibeam antennas with a reduced complexity should be developed. The beamforming could be analogue, digital or hybrid. A significant simplification can be obtained by limitingthe multiple beams directions in a limited portion of the field of view where the majority of the satellitesareexpected to be visible. In facts, the number of active controls in the antenna is proportional to the extension of the angular field of view. Another simplification can be obtained by assuming a minimum angular separation between two contiguous beams corresponding to two different satellites. The design must be customisable based on the longitude and latitude of the gateway station considering also the orbital position and orientation of the constellations to be served. By applying these simplifications and customisations, significant simplifications in the gateway antennas should be obtained.The activity will design, manufacture and test a singleaperture Ka or Q/V band gateway multibeam antenna, capable to serve multiple satellites located in a large field of view. At least twopromising technical solutions will be identified and studied. Trade-offs will be carried out and the most promising concept willbe selected and implemented in a reduced scale prototype. The developed multibeam gateway antenna will be tested in a relevant environment establishing a link with a real satellite and scanning two independent andsimultaneous beams.","ecosrequired":false,"establishment":"ESTEC","firstPublicationDate":"2026-06-01T16:32:13","id":188559,"idEra":25187,"initiatingService":"RNC-FTG","ipmeasure":"N/A","isArchived":false,"isCancelled":false,"isReissued":false,"isToBeReissued":false,"issueQuarter":"263","lastUpdateTime":"2026-07-29T09:43:51","lastUpdateUser":"ltena","openDate":"2026-07-22T14:30:28","priceRange":"> 500 KEURO","programmeReference":"IC1 - Advanced Techn","tanumber":"1-13564","title":"MULTIBEAM GATEWAY ANTENNA FOR SATCOM CONSTELLATIONS (ARTES AT 6B.147) - EXPRO+","directorate":"Dir. of Connectivity  Secure Comm.","countries":[{"id":1},{"id":62},{"id":26},{"id":24},{"id":23},{"id":22},{"id":19},{"id":17},{"id":16},{"id":15},{"id":13},{"id":12},{"id":11},{"id":10},{"id":9},{"id":7},{"id":6},{"id":5},{"id":4},{"id":2},{"id":67},{"id":168}],"products":[{"id":362},{"id":357},{"id":356},{"id":25},{"id":24}],"technologies":[{"id":214},{"id":202},{"id":200}],"status":{"id":2},"tenderType":{"id":5},"isFavourite":false,"eraVersion":1,"stageNumber":null,"isNew":false,"isUpdated":false,"declarationOfCompliances":["All the required declarations of compliance have been addressed and included in our proposal's Cover Letter."],"keyAcceptanceFactors":["The Tenderer confirms that the tender Cover Letter and the Detailed Proposal contain a price type compliant with the one requested in the ITT;","The Tenderer confirms that the tender Cover Letter and the Detailed Proposal contain a binding price;","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to be compliant with the “Non Benefits Requirements” (see section 1.8 of the EXPRO/TC);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to accept the conditions established for “Non commitment by the Agency in competitive procurements” (see section 1.7 of the EXPRO/TC);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to fulfil the requirements concerning “Free Competition” (see paragraph 11 of the Cover Letter of the Proposal Template);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to satisfy the “Eligibility Requirements” (see section 1.1 of the EXPRO/TC);","ARTES 4.0 Core Competitiveness Generic Programme Line - Component A: Advanced Technology:\nThe Tenderer confirms that supporting evidence of the authorisation of funding from the relevant Participating State(s) is provided as part of the Tender cover letter and in accordance with the requirements of section 4 of the Cover letter to the present ITT","The Tenderer confirms that the tender is compliant with the budgetary limit applicable to the ITT;"],"evaluationCriterias":[{"criterion":"Background and experience (related to the particular field concerned) of the company(ies) and staff [OPTION], including adequacy of the proposed facilities END OPTION]","weightingFactor":"25%"},{"criterion":"Understanding of the objectives of the activity and discussion of the problem areas, and adequacy of the programme of work","weightingFactor":"60%"},{"criterion":"Adequacy of the time dedication and costing, compliance with administrative tender conditions and acceptance of the contract conditions","weightingFactor":"15%"}],"entities":[],"procurementProposal":null,"responsible":"Nathalie Dorval","updateReason":"Tender Clarification has been published"}],"totalNew":0,"totalUpdated":0}
