In recent years there have been many research works are going on in the design of antenna system as it is the main source for any communication system. The horn is nothing more than a hollow pipe of different cross sections, which has been tapered (flared) to a larger opening. The type, direction, and amount of taper (flare) can have a profound effect on the overall performance of the element as a radiator. The Horn Antenna is widely used in the EMC measurement, radar and communication system. Especially for wireless broadband applications horn antennas are the best choice. Horn is one of the simplest and probably the most widely used microwave antenna. In this paper we present the design and radiation pattern analysis of a specific horn antenna i.e. Pyramidal Horn. The paper contains introduction to horn antennas, the pyramidal horn, design of Pyramidal horn and conclusion.

Design and Simulation of Horn Antenna in x-Ku Band for Satellite Communications

ISSN: 23490-0845, Vol 1, Issue 10

Horn antennas are widely used antennas in satellite applications mainly because of their physical robustness and capability to operate at high frequencies. In this work an attempt has been made to design a pyramidal horn antenna along with associated waveguide to operate in X-Ku band (9.5 to 14.5 GHz). The design was simulated using High Frequency Structure Simulator (HFSS). HFSS is a widely used tool when it comes to design and simulation of any antenna system. Initially by using design formulas, the dimensions of the horn structure and waveguides are found and then they are fed into HFSS to simulate in the mentioned frequency band. The performance parameters like return loss, radiation pattern, directivity and cross-pol isolation were considered for the simulation. Finally, with this design we will be able to reduce the operation costs in launching any communication satellites for broadcasts.

Analysis of Pyramidal Horn Antenna for J-Band Application

Sciprints, 2016

In this research paper, design and development of pyramidal horn antenna for J-band application is reported. It is particularly designed for 17 dB gain and half beam width about 25 degrees at 6.93 GHz. Horn aperture, horn axial length and distance from the throat of the antenna to aperture are the main design constraints which are calculated and used for the antenna design and simulation. Beam width in E-plane and H-plane horn is calculated and it is 19.18 dB and 22.86 dB respectively. The reported antenna design shows good performance for J-band in radiometry, satellite, and radar applications.

Design and Testing of Pyramidal Horn

Horn antennas are widely used in microwave frequency range. They are also used as standard for calibration and gain measurements of other antennas. They are used as feed elements for reflectors and lens antennas and universal. In addition they also find use in radio frequency heating, nondestructive testing and biomedicine. An optimum pyramidal horn to provide gain of 20dB and center frequency 9.5GHz is designed. Using aluminum sheet of thickness 2mm, the antenna is fabricated. The performance parameters like gain, directivity, impedance and s parameters are evaluated analytically as well as experimentally. The results are discussed. The scheme of measurement can be implemented even in the absence of costly equipment like power meter or network analyzer to get an idea of the antenna parameters.

Design and simulation of Pyramidal Horn Antenna for NDT Applications

This paper describes a pyramidal horn antenna design which it works in a microwave domain. His operating frequency is 4.7 GHz. The parameters of the antenna were measured through its numerical modeling using HFSS (High Frequency Structure Simulator) electromagnetic simulation software. HFSS has the capability to calculate and plot a 3D image depicting the real beam of the gain. The obtained results show that an antenna gain of 12.90 dB was obtained at the frequency of 4.7 GHz, which means that the antenna is properly adapted to the transmission systems. This antenna will be used for non destructive testing (NDT) application, such as detection of cracks in different materials, materials characterization.
