A Performance Assessment of A Slotted Reconfigured Microstrip Patch Antenna for Multi-Wireless Applications

Abstract

A Dual Frequency reconfigurable antenna is presented in this paper. Achieving Reconfigurability in the resonant frequency of microstrip patch antenna by introducing slots and structure alteration has been proposed. The proposed designs of rectangular microstrip patch antennas are resonating at 5 and 2.1 GHz(reconfigured) respectively. Modeling of reconfigurable antenna to achieve max size reduction by introducing partial ground concept and patch structure alteration has been used. Modelling of reconfigurable antenna for multiband operation is the one of the major challenges and the solution for this challenge is by introducing the slots over the patch of the antenna. To achieve wider bandwidth for wireless applications changing the structure patch and partial ground plane concept is proposed. Reconfigured antennas are well known for their characteristics like lightweight, low profile, and compact enough to be employed in smart wearable technology as well as portable electronics (such as, watches, smartphones, iPads, PDAs, and laptops), A Finite Element Method (FEM) and numerical Finite Integration Technique (FIT) are used in CST Microwave studio to estimate the antenna scattering and far-field characteristics.
