Abstract: In this communication, we propose a low-sidelobe dual-polarized waveguide slot phased array antenna, operating in the X-band, based on array coding techniques. The horizontally polarized (HP ...

Check out the latest episode of our popular tech podcast. Conventional image sensors capture a frame at a time while event-based vision sensors track changes of individual pixels. In this episode of ...

Abstract: This letter presents a novel method for constructing a metasurface phased array antenna (MSPAA) using metasurface antenna (MSA) elements. To ensure the MSPAA has a low profile, wide ...

"The world has all been based on GPS. But what happens when you lose it? How do you navigate?" From satellite TV broadcast hijacking to jamming and spoofing of satellite navigation systems ...

According to a paper published on February 18, all missiles were successfully detected and tracked by a new dual-band (S/X) phased array radar system, before hitting the target with 100 per cent ...

"We have improved the performance of every system and sub-system on board, including phased array antennas, processors, solar arrays, propulsion systems, and optical inter-satellite links ...

The satellites feature significant upgrades over two prototypes ULA launched on an Atlas V in 2023, according to Amazon, including improved phased array antennas, processors, solar arrays ...

The first quarter of 2025 saw six companies raise at least $100 million in investment. Of those, three went to quantum hardware companies, with major investment into neutral atom, superconducting, and ...

This involves sending data from the internet, through our ground infrastructure, up to the satellites, and down to customer terminal antennas, and then repeating the journey in the other direction.

These could be unrelated, or be pathfinders for new generations of satellites for these projects, and test systems such as propulsion, power, thermal control and phased array antennas ...
