At its most compact, the antenna is a hollow ring that stands just over 1 inch tall (2.5 cm), about 5 inches (12.5 cm) across—not much larger than a bracelet—and weighs 1.4 ounces (40 grams ...

The uplink side of [Tech Minds]’ antenna is a helical design, with three-and-a-half turns of heavy copper wire and a tuning section of copper strapping that attaches directly to an N-type connector.

Stutzman and Barts tried many new helix antenna design concepts. They bent lots of wire in unusual shapes, and then tested them for antenna performance.

Helical Antenna Makes Satellite Reception Reliable And Easy March 27, 2006 Receiving a signal from a geosynchronous satellite 22,300 miles out or a GPS satellite over 10,000 miles away is a challenge.

Portland, Ore. – A four-year skunk works effort at the University of Rhode Island in Kingston has cut the size of an antenna by as much as one-third for any frequency from the kHz to the GHz range.

Harxon has released the multi-constellation D-Helix Antenna at the 2017 Intergeo trade show, held Sept. 26-28 in Berlin, Germany. The Harxon booth is located at Hall 4.1, Stand C4.013. The industrial, ...

Developed by researchers at Stanford University in the US and the American University of Beirut (AUB) in Lebanon, the new antenna has a mass of just 39 g and consists of counter-rotating helical ...

D-Helix Antenna: The multi constellation antenna is capable of superior tracking signals from 4 satellite constellations, including GPS L1/L2 L-Band, GLONASS L1/L2, BDS B1/B2/B3 and Galileo. The ...

With their own innovative design assembled into a potentially revolutionary prototype, the students are well on their way to equipping the space industry for greater scientific impacts. The Senior ...

Usually, the interaction of such nano-antennas with an electromagnetic field is determined using numerical methods. Each helix geometry, however, requires a new numerically expensive calculation.

A spin-off of GPS company Symmetricon has developed an antenna that could reduce the amount of radiation absorbed by mobile phone users, measured in terms of specific absorption rate (SAR), by as much ...
