MIT researchers have developed a low-power scanning reflectarray antenna that improves anti-jamming satellite communications ...

THE ANTENNA IS A CRITICAL COMPONENT OF ANY GNSS RECEIVING EQUIPMENT. It must be carefully designed for the frequencies and structures of the signals to be acquired and tracked. Important antenna ...

Preventing adversaries from interfering with communications is crucial to national security. Tactical satellite ...

Keeping satellite communications secure is becoming more important as space becomes increasingly crowded. Military and ...

Use the Yagi-enhanced, log-periodic pattern to build a homemade long-range tv antenna consisting of the element array the framework, and the mast. A few years ago, some friends of mine shed city life ...

“This study presents a simple, miniaturized, and low-profile multiple-input multiple-output (MIMO) antenna operating at 29 GHz with reduced mutual coupling between the antenna elements for futuristic ...

Historically, testing Controlled Reception Pattern Antenna (CRPA) systems in a laboratory has been a very difficult process — dynamics were limited and test duration was usually short. Often, dynamic ...

Global navigation satellite system (GNSS) technologies such as global positioning system (GPS), GLONASS, COMPASS/Beidou, Galileo, QZSS, IRNSS/NavIC, and others are increasingly crucial for terrestrial ...
