The antenna normally operates in a vertical configuration. It looks like it might be simple to make some version of this without anything exotic. Let us know if you try! Helical antennas aren’t ...

If you want to reach a satellite in geosynchronous orbit it’ll take a little more effort, and this dual-feed helical “ice cream cone” antenna could really help. Until recently, the dream of ...

A deployable spring antenna design with the ability to stow to ¼ its length, survive launch, match the performance of rigid antenna counterparts, and scale to different frequencies, brings new ...

Quadrifilar Helix Antenna is omnidirectional circularly polarized antenna. It's ability to receive or transmit a tight beam of circularly polarized radiation while minimizing unwanted radiation ...

The bi-stable deployable quadrifilar helix antenna passively reconfigures its radiation characteristics in terms of pattern and polarization. | Image courtesy of Reconfigurable & Active Structures ...

FPV diversity is a feature that allows your goggles or receiver to switch between two or more antennas, depending on which one has the strongest signal at any given moment. This can help you avoid ...

Abstract: Measuring the pointing angles of high-power microwave (HPM) helical array antennas presents significant challenges, resulting in a lack of effective angle control schemes in current research ...

Abstract: The derivation of an analytic formula for the impedance of cylindrical and helical antennas in cold magnetoplasma is outlined. The method used is a conventional one reducing to integration ...
