A modified bow tie antenna with U-shape slot for Wireless applications

This paper presents a study on bow tie antenna with U-shape slot, designated for the Wireless applications. It is designed to work on a thick substrate (h = 1.6mm) with a high dielectric constant ( = 4.4) operating at three frequencies (2.4, 4 and 5GHz). Two U-shaped slots are introduced in the both sides of bow tie antenna in order to achieve a very low return loss at these frequencies. The antenna is simulated with HFSSv11 simulator. The proposed antenna can exhibit minimum return loss, Omni-directional radiation pattern, wide impedance bandwidth, VSWR<2, and the stronger current distribution throughout the antenna.
