Quasi-optical systems are frequently designed on the assumption that the propagating radiation approximates to a fundamental-mode Gaussian beam; this can be described as a paraxial approximation to a solution of the scalar wave equation. Gaussian beam theory can be used to generate designs for ...
An array feeder for a reflector or a lens provides considerable flexibility in the beams that can be produced. A single beam could be obtained by combining all elements; multiple beams can be created with clusters of subarrays or the elements combined in such a way that a beam is steered b...
Reflectarray antenna for communication satellite frequency re-use applicationsA dual-polarized antenna includes a planar line or surface array of reradiating elements of two different polarizations. Each reradiating element in one embodiment is a short-circuited vertical or horizontal dipole. The vertical...
This paper reports a most complex shaping of a dual gridded reflector (DGR) antenna for a stringent requirement. There is a requirement of a service area (India with islands) and 10 spatial isolation zones. This stringent RF requirements awake severe design complexity and challenges, which is ...
A dual-band monopole antenna with coplanar waveguide feed, with artificial magnetic conductor as reflector has been designed and simulated using CST Microwave Studio. The antenna operates effectively at 3.5GHz with the integration of AMC it operates at one additional band 1.5GHz for L-Band ...
(AMC), and parasitic strips. By utilizing the Brillouin dispersion diagram, the AMC is designed as the antenna reflector. It has a wide in-phase reflection bandwidth of 54.7% (1.54-2.70 GHz) and a surface-wave bound range of 0-2.65 GHz. This design effectively reduces the antenna profile ...
(sub-) reflectors. These attractive features, combined with the possibility of a fine control and shape tailoring of the aperture field, result in a number of interesting antenna devices recently proposed in literature. Challenging designs have been also made possible through the evolution of MTSs ...
Reflector antenna systems FSS’s are often used to filter out electromagnetic waves at specific frequencies. The FSS have found uses for its spatial filtering feature in expanding the operational bands of a reflector antenna system. The number of reflector antenna feeds has grown as a result of ...
log periodic, aperture, microchip, reflector, lens, array, and traveling wave. So knowing each antenna and its purpose is mandatory to use in suitable applications. For that, this article discusses an overview of one of the types of wire antenna namelydipole antenna, and its working with appli...
A corner reflecting antenna is truncated by a reflecting plate. Two rows of ipoles are placed near the throat of the corner reflector (but in front of reflecting plate) and aligned parallel to sides o
