Cosmonauts Successfully Replace Antenna But Point It In The Wrong Direction The astronauts had the task of replacing the electronics box fixed to a high-gain antenna, which helps the Russian ...

An antenna's directive gain, as implied in the math above, is defined by its region of maximum directivity of the main beam. If the half-wave dipole is perpendicular to the ground, it is ...

Antenna gain and directivity are in comparison to an isotropic antenna - which is an ideal antenna that radiates evenly in all directions. Directivity is a comparison of the maximum power measured, ...

Antipodal Vivaldi antennas (AVAs) have emerged as a critical component in advanced wireless communication and sensing systems, owing to their inherently wide bandwidth, high gain and stable ...

We have been able to conclude that using an isotropic antenna, an RFID reader might achieve a read range of a few meters with 1 watt of output power. This configuration might be fine ifRFID tags of ...

The antenna works on the principle of measuring the phase difference between the nine elements and the central reference. As well as the vehicle mounting kit, there is an optional tripod with ...

The Defense Innovation Unit is looking to find a prototype small high-frequency direction-finding antenna that it could mount on a fixed-wing aircraft. The U.S. Department of Defense wants a ...
