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 ...

The need for significant improvements in radar continues to be an ongoing concern for the Department of Defense (DoD). One of the most impressive developments addressing this need is a high-resolution ...

Beamforming, based on multiple-input, multiple-output (MIMO) phased-array antennas, looks to make up a component part of the overall 5G cellular technology. While phased-arrays have been the basis of ...

Phased array antenna calibration is essential for realising the full potential of modern beamforming applications in areas such as wireless communications, radar systems and satellite transmissions.

CesiumAstro is jumping into the in-flight connectivity (IFC) market, unveiling a new multi-beam flat panel terminal for aviation on Monday, March 13. It is an active phased array that can support ...

The operation of ground stations and phased-array antennas. How SDRs are integrated into ground stations. Issues to be considered when incorporating SDRs into phased-array antennas. Examples of ...

Analog Devices is aiming at X-band and Ku-band phased-array antennas with an active analogue beam-forming chip that includes four channels of transmit and receive gain and phase control, plus a ...

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 ...

The normal buyers of Phased Array satellite antennas are usually the military or public-service operators, or aircraft, train or bus operators. Their budgets can afford the thousands of dollars for a ...
