Get ACB-4 Comtek Systems 4 Square Or 2 Element Phased Array

Phased Array Antennas have been used for military applications for years. In fact, they were created to be used in radars systems but their applications have grown over the years. They are now used in broadcasting, space probe communication, weather research, optics, human-machine interfaces, etc.

A four-square antenna array is a single band directional antenna system. It uses four current-fed vertical antennas positioned at the corners of a 1/4-wavelength on a side square. In order to produce deep nulls each element must have equal currents and proper phase shift.

Types. Phased arrays take multiple forms. However, the four most common are the passive electronically scanned array (PESA), active electronically scanned array (AESA), hybrid beam forming phased array, and digital beam forming (DBF) array.

Phased Array Antennas can be of various types however, there are four commonly used types: Passive Electronically Steered Array (PESA) Active Electronically Steered Array (AESA) Digital Beam Forming (DBF) Hybrid Beam Forming (HBF)

The three types of phased array antennas are 1) linear array, 2) planar array, and 3) frequency scanning array.

Active- element phased-array radar employs an antenna composed of an array of elements, each with their own amplifier functions. This can be contrasted with a passive-element phased-array radar, whose elements receive microwave energy from one transmitter source.

It is a way to direct waves of radiation toward a desired direction. Advertisements. A phased array is also known as a phased antenna system.
