Preventing adversaries from interfering with communications is crucial to national security. Tactical satellite ...

MIT researchers have developed a low-power scanning reflectarray antenna that improves anti-jamming satellite communications ...

In the realm of modern satellite communication, SpaceX's Starlink system stands out for its innovative use of phased array antenna technology. This advanced technology is the backbone of Starlink's ...

WASHINGTON — The U.S. Space Force is launching a new competition for mobile satellite-control antennas, formally restarting a program it canceled after abandoning a $1.7 billion contract with ...

The Defense Innovation Unit has awarded at least two contracts to build prototype phased array antennas which are capable of connecting with multiple satellites simultaneously. (Lockheed Martin image) ...

This communication presents a polarization reconfigurable antenna array (PRAA) with Multi-input Multi-output (MIMO) formation for 5th generation (5G) millimeter wave (mm-Wave) communications. At first ...

Phased array technology is far from new. Phased-array antennas have been used for decades in a variety of military applications. Now, however, their use in 5G systems in the Band 2 frequency range is ...

If you watch old science fiction or military movies — or if you were alive back in the 1960s — you probably know the cliche for a radar antenna is a spinning dish. Although the very first radar ...

This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems. It examines the new capabilities recently added to the NI AWR Design ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

For some applications single element antennas are unable to meet the gain or radiation pattern requirements. Combining several single antenna elements in an array can be a possible solution. This ...

The design of an array of stacked leaky-wave antennas in groove gap waveguide technology is presented in this work. The proposed array is formed by simply stacking a number of leaky-wave antennas one ...
