What is microstrip antenna array?

The antenna has been designed as arrays of patches, where number of elements, spacing’s and feeding currents has been optimized to fulfil the requirements of low side lobe level and good cross polarization. The operating frequency of array is from 12 to 18 GHz.

What is antenna array and why it is needed?

An antenna array (often called a ‘phased array’) is a set of 2 or more antennas. The signals from the antennas are combined or processed in order to achieve improved performance over that of a single antenna. The antenna array can be used to: 1. increase the overall gain.

What is the maximum range for 60 GHz system communication?

Telecommunications. In the United States, the band 36.0–40.0 GHz is used for licensed high-speed microwave data links, and the 60 GHz band can be used for unlicensed short range (1.7 km) data links with data throughputs up to 2.5 Gbit/s.

How is the directivity of an antenna limited at 60 GHz?

Antenna directivity is limited by the physical principle of diffraction that states that the beam width is inversely proportional to the operating frequency. Therefore at 60 GHz, the beam width is far narrower than at the lower frequency unlicensed bands.

What is the capacity of a 60GHz radio?

Modern V-band 60GHz radios from CableFree are easy-to-deploy, cost-effective, wireless Gigabit Ethernet point-to-point bridges operating in the 60 GHz millimeter wave V-band, delivering full-duplex capacity of up to 1 Gbit/s over distances of up to 1km or more.

How are the elements of an antenna array connected?

An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in…

Which is another name for a phased array antenna?

It is usually another name for a Yagi-Uda antenna . A phased array usually means an electronically scanned array; a driven array antenna in which each individual element is connected to the transmitter or receiver through a phase shifter controlled by a computer.
