Design of Dual band Slotted Microstrip Patch Antenna for Wi-Fi & Wi-Max Applications

摘要

This paper highlights the proposed design for a dual band slotted frequency reconfigurable microstrip patch antenna fed through a 50Ω coaxial feed using inset type of a feeding system over the FR4 substrate for resonating between Wi-Fi and Wi-Max frequency bands. The patch antenna is proposed to tune between two frequencies i.e. Wi-Fi frequency (2.4GHz) and the Wi-Max (3.5GHz) with the help of slots. The proposed structure resulted in a gain of 1.94dBi and 3.31dBi for the lower and the upper frequency bands respectively the measured radiation patterns were Omni directional in the higher band.
