A Compact Antenna Array for Smart Grid Application

Advances in two-way co mmun ication are enabled by powerful, co mpact and low cost antenna design that can be easily implemented in today's compact communication devices. The paper presents a novel, compact, low pro file wide bandwidth microstrip antenna array. The total size of the antenna array is 29mm x 22mm x 2mm. Th is new design offers a wide fractional frequency bandwidth of about 36% with a gain fro m 4.7d B-6.6dB over the frequency band (5GHz - 7.2GHz). The antenna design and simu lation was carried out using ANSYS' HFSS software. The applicat ion of the antenna suits many communicat ion sensory devices and systems currently proposed for interfacing with home and industry energy harvesting devices considered to be one of the most challenging elements in building reliable s mart grid infrastructure.
