Inmarsat Satellite Antenna Gain

The measured results show that in the whole maritime satellite communication work band the vswr is less than.

Inmarsat satellite antenna gain.

Gain typical 8 5 dbic minimum 6 0 dbic over 90 of specified inmarsat hemisphere. Satellite communications msc are relatively large and heavy especially shipborne directional inmarsat b and fleet 77 antenna systems. Multipath rejection exceeds 10 db rejection at 5 degrees elevation. Isat is a british satellite telecommunications company offering global mobile services.

The unit provides over 90 sky coverage. Polarization performance right hand circular. Axial ratio is less than 6 0 db for all steering angles and all frequencies of operation within coverage region. Low gain satcom antenna covering inmarsat frequency range of 1530 to 1559 mhz and 1625 5 to 1660 5 mhz designed to meet sb200 class 15 service.

Gain typical 8 5 dbic minimum 6 0 dbic over 90 of specified inmarsat hemisphere. Axial ratio is less than 6 0 db for all steering angles and all frequencies of operation within coverage region. Intermediate gain antenna 332kbps iga combines high quality voice communications with a symmetric background data connection of up to 332kbps per channel. The broadband coverage of the antenna also includes frequencies of 1616 to 1626 5 mhz for iridium satelite services voice and data applications.

A high performance l band inmarsat aero std c patch antenna with a gain of 3 5dbi and a female sma connector. Up to four channels per aircraft for concurrent voice and data links with the ability to add four more voip connections with each. Over the past two decades the directional antenna system which comprises the. Polarization performance right hand circular.

Upon completion the four inmarsat 5 satellites will join inmarsat s. Multipath rejection exceeds 10 db rejection at 5 degrees elevation. The enfusion amt 3800 is an arinc 781 high gain antenna hga used to receive and transmit voice and data from a moving aircraft via the inmarsat satellite network and supports multi channel swiftbroadband class 6 services. The optimal antenna structure for inmarsat application has been fabricated and measured.
