Abstract

Aim: The principle of eliminating the frequency reuse in the mobile Ad Hoc system among the sectors of theunit cell using Multi Inputs Multi Outputs (MIMO) antenna array is investigated in this paper. Antenna Design: The size of the proposed antenna array is 10◊10 cm 2 to obtain a bandwidth around 1 GHz. The single antenna element is constructed from sub -patches that are connected with feeding network through pin diodes, as switches, that are mounted on an FR-4 substrate. Antenna Performance :The antenna elements are characterized from 0.8 GHz to 2 GHz in terms ofS-parameters and radiation patterns with differ ent switching OFF/ON categories. Methodology: A numerical investigation based on Finite Integral Techniques (FIT) of Time Domain (TD) formulations is conducted using CST MWS to evaluate the antenna performance. A Frequency Domain (FD) solver based on CST f ormulations is conducted for validation. Original ResearchArticle
