We present a balun-free coax-fed helical antenna for microwave ablation. The proposed antenna produces a localized specific absorption rate pattern at the desired frequency of operation without using ...
2. The quadrifilar helix antenna can easily be compacted or extended to modify its signal pattern with definable, consistent results.
Helical antennas aren’t new, but this is an unusual construction. They are p opular as satellite antennas because of their polarization characteristics among other things. Continue reading “No ...
Developed by scientists from Stanford University and the American University of Beirut, the prototype device is a form of what's known as a helical antenna.
New, portable antenna could help restore communication after disasters Researchers from Stanford and the American University of Beirut have developed a lightweight, portable antenna that can ...
A planar helical antenna is presented for achieving wideband end-fire radiation of circular polarization while maintaining a very low profile. The helix is formed using printed strips with ...
Redwire in a January 2022 news release said it was under contract to deliver three L-band Link-16 helical antennas for the Space Development Agency’s Transport Layer Tranche 0.
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 ...
