A controlled radiated pattern antenna can be an effective way to protect GPS receivers against jamming. A new CRPA, composed of seven elements, works on the E5a, E5b, E6, L2, and L1 bandwidths. This ...

In the radiofrequency regime, a typical antenna design for high directivity is the Yagi–Uda antenna, which essentially consists of a one-dimensional array of antenna elements driven by a single ...

The sky-facing side of the phased array, the key element that allows the antenna to track the rapidly moving Starlink satellites as they pass overhead, is also laminated to a stack-up comprised of ...

An active antenna, in contrast, has a single amplifier per radiating element, for both transmit (TX) and receive (RX). In general, passive antennas are less complex, while active antennas provide ...

The impact of passive antennas on 5G network performance is substantial. According to the Ericsson-ABI Research article, a mere 11 per cent improvement in beam efficiency can yield an 18 per cent ...

Conventional 5G system structures require use of an antenna panel for each terminal when simultaneously transmitting to multiple terminals. Now, by controlling with high accuracy the phase (angle) of ...

Compact and lightweight, the R&S ADD507 direction finding (DF) antenna covers 9 MHz to 8 GHz, reducing the need for multiple antennas. Expanded VHF coverage improves weak signal detection, making the ...

TenXc, a Canadian company formed in 2002, used some algorithmic work it planned to apply to adaptive beam forming, and designed a passive bisector antenna array that is easy to deploy in operating ...

If you’ve ever cast your eye towards the rooftops, you’ll be familiar with the Yagi antenna. A dipole radiator with a reflector and a series of passive director elements in front of it,… ...

Posted: Feb 13, 2007 Optical antenna with a single carbon nanotube (Nanowerk Spotlight) For several years now, researchers have documented the many intriguing mechanical and electrical properties of ...

In the 1950s, atomic clocks revolutionized precision time-keeping. Now we may be on the verge of so-called "atomic radio," thanks to the development of a new type of antenna capable of receiving ...
