Development of 1.8 M Diameter Dish Reflector using Fiberglass Materials at Ku-Band Applications

Abstract

This paper describes the design, simulation and development of parabolic reflector using fiber glass. The antenna is 1.8m in diameter, for operation at Ku band (10.95-12GHz). An f/d ratio of 0.43 was chosen and other parameters were computed. The S parameters for the antenna were obtained using Design-Expert 6.0.8 Software Version and Advance Design System (ADS). The properties of the antenna such as bandwidth, beam width, gain, directivity, return loss and VSWR were obtained. offers high efficiency and high gain. The fiberglass has good surface accuracy with a light weight of 20 kg.

Design and Simulation of a 3.5 GHz Pyramidal Horn Antenna for IoT and High Speed 5G Wireless Technology Mobile Networks

“…The cut-off frequency, operating frequency and upper frequency are 3.15, 3.5 and 3.85 GHz respectively. The dominant mode of the waveguide is the mode with minimum value of m and n which the cut off frequency will be lowest as depicts in Equation .(1) [11,12]. In this study, the transverse electric mode is selected as dominant because it has the lowest attenuation of all modes in a rectangular wave guide.…”

“…The aperture Q is designed from Equation. (12), with q = 3.36 cm, The axial length LE from the E-plane view is determine by referring to triangle ABC in figure 2 (a) using Pythagoras theorem as follows,…”
