What is dual band microstrip antenna?
In this paper, the design of a dual-band microstrip antenna is presented. The proposed design is based upon the T-shaped structure with two strips. The antenna is fed by coaxial probe feeding. The presented antenna gives wide bandwidth for both frequency bands. The antenna is simple in structure and is compact in size.
What is dual linear polarization?
Dual linear polarization antennas possess two linear polarization modes that are perpendicular to each other. The two linear polarization modes can be excited using two ports of the same antenna. The type of polarization in dual linear polarization antennas can be either vertical, horizontal, or slant polarization.
What is meant by polarization in antenna?
The polarization of an antenna is loosely defined as the direction of the electromagnetic fields produced by the antenna as energy radiates away from it. These directional fields determine the direction in which the energy moves away from or is received by an antenna.
What is the use of polarization?
Polarization is used in sunglasses to reduce the glare. Polaroid filters are used in plastic industries for performing stress analysis tests. Three-dimensional movies are produced and shown with the help of polarization. Polarization is used for differentiating between transverse and longitudinal waves.
What is the difference between dual-band and single band WIFI?
A Single-band router uses the 2.4GHz band and is limited to one wireless signal. A Dual-band router uses two bands: 2.4GHz and 5GHz, which means that they transmit two simultaneous wireless signals, providing better performance, and compared to a single-band router, a dual-band router is easier to set up.
What is a polarized antenna?
Antenna A structure or device used to receive or radiate electromagnetic waves. Circularly polarized antenna An antenna that radiates circularly polarized waves, which are waves in which the electric field vector rotates in a circle as the waves travel.
Which polarization is best for antenna?
For most antennas it is very easy to determine the polarization. It is simply in the same plane as the elements of the antenna. So a vertical antenna (i.e. one with vertical elements) will receive vertically polarised signals best and similarly a horizontal antenna will receive horizontally polarised signals.
