Ultra-Wide Band Antenna Design using Stairs for Personal Area Network Wireless Application

Objectives: This paper explains about the staircase antenna with characteristics of ultra-wide band (UWB). The design of proposed work describes stairs along the radiating patch with micro strip feed. Method/Statistical Analysis: The projected ultra-wide band antenna is designed and simulated using High Frequency Simulation Software (HFSS). Findings: The simulation and Measured result of the antenna prove that it has a good impedance matching over the UWB frequency range from 3.5 - 10.4GHz. The VSWR is less than 2 for entire operating frequency range. This antenna finds its uses in WiMax and Wi-Fi without interference. Stair Case patch design is chosen to get ultra wide bandwidth and strips are introduced to get band notch characteristics. Applications: The proposed antenna is suitable for its use in WPAN applications and for short range communication.
