On-Board Wide Broad Bandwidth Switching Linear and Planar Antenna Arrays for Industrial Use in an Era of Industrial Revolution

Abstract

The paper outlines the analysis of horn antenna and arrays of microstrip antenna for onboard high data rate transmission in the X-Band ( 10 Ghz). The antenna arrays consists of eight equispaced linear array elements with beam formation and gain of 20 dB. In satellite communication, we require the transmission of waves which are circularly polarized. This is achieved by placing helical antenna elements, which has the advantage that the antenna is broadband and transmission is circularly polarized. This paper also considers method of feeding the linear array, where only a first few elements produce radiation and the pattern is highly distorted. Linear array feed from both ends will produce uniform excitation so that the entire array is excited, with low distortion of pattern.
