Multisegment microstrip patch antenna with Y-shaped feed

Abstract

A new antenna structure comprising of multiple radiating microstrip patches, representing a figure of digit eight, proximity fed by a microstrip line is proposed. On a double-layered substrate of FR4, this antenna achieves multiband functionality in the range of 3.81-12.42 GHz, which covers IEEE 802.11a standards and is suggestive of reconfigurability in frequency and pattern. Details of the antenna design, measured and simulation results are presented.
