There are many different types of antenna designs, with some of the most common ones being monopole, dipole, beam, zig-zag, horn...
a type of electromagnetic radiation, enable the transfer of data over the air, eliminating the need for wired connections. Think of an antenna as the “ear” or “voice” of a wireless system, capturing signals from the environment
There is a huge variety of different types of antenna or aerial used for terrestrial TV and radio reception. The antennas have different shapes and sizes and many look different to the others.Knowing something of the different types as well as the basic specifications that ...
As Antenna resides between cable/waveguide and the medium air, the main function of antenna is to match impedance of the medium with the cable/waveguide impedance. Hence antenna is impedance transforming device. The second and most important function of antenna is to radiate the energy in the de...
This antenna is designed with a coil that carries a radio frequency current. This loop may be in any form by bending the wire into different shapes, soloop antenna shapesare; rectangular, circular, square, hexagonal, or triangular based on the convenience of the designer. The current throughout...
Generally, the strip/patch & the feed lines are photo-etched on the surface of the substrate. There are different microstrip antenna shapes like square, dipole, rectangular, circular, elliptical, and dipole. We know that patches can be formed in various shapes but, because of the easy in fab...
patch antennaproximityreturn lossribbontrapezoidIn this paper there are four different shapes of proximity patch antennas (straight, trimmed, trapezoid and ribbon). The minimum input match achieved with the straight proximity patch antenna as -39.68 dB. The maximum gain is achieved with the ribbon ...
Apart from the occasional horn of a maneuvering rocket or the spike or dish of a communications antenna, the shapes from which she had been assembled shared a geometric purity, and all alike shone dazzling white under their fresh coats of electro-bonded paint. Two days later heavy tugs ...
This is a retroreflector that includes three mutually perpendicular and intersecting flat surfaces that reflect waves directly to the source, although converted. The three intersecting surfaces in this antenna have frequently square shapes. This is a very useful device for the calibration of radar ...
This research investigates the performance of a diagonal, conical, and octagonal horn antenna at 1.6 THz in terms of antenna patterns and Gaussian coupling efficiency. 展开 会议名称: 2008 33rd International Conference on Infrared, Millimeter and Terahertz Waves: Pasadena, CA 15-19 September 2008 ...
