ESA fired a ‘non-explosive actuator’ in stuck bracket of the ESA JUICE spacecraft's RIME antenna to jar in loose. Mission ...

A TV antenna may seem like a relic from a bygone era, but they're actually becoming more popular again. But is it even practical to use an antenna today?

Designed and manufactured in the U.S., these antennas deliver exceptional radio frequency (RF) performance from L-band (1.35 GHz to 2.5 GHz) to S/C-band (2.2 GHz to 2.5 GHz and 4.4 GHz to 4.49 GHz).

Air Traffic Controllers use Automatic Dependent Surveillance-Broadcast (ADS-B) as an alternative to secondary radar to track aircraft. The ADS-B is transmitted by the aircraft and contains information ...

Global carbon dioxide emissions from fossil fuels hit a record 38 billion tons last year, putting the world’s most ambitious ...

Abstract: High-frequency (HF) ground-wave radars employing compact antenna arrays are advantageous in practical applications because of their convenient deployment. However, the direction-of-arrival ...

These applications have been validated by one of the following councils: Southend Council, Basildon Council, Rochford Council, or Castle Point Council. For more public notices, visit ...

Abstract: A miniaturized, dual-band, circularly polarized microstrip antenna (CPMA) for satellite mobile phones was designed. Two miniaturized radiation elements using folded structures are stacked ...

Boeing knows a thing or two about electronically steerable antennas (ESAs). For nearly 30 years, it has been designing, qualifying and delivering active phased array systems to support aeronautical ...
