Bandwidth Enhanced Multislot Rectangular Patch Antenna for UWB and X Band Wireless Applications

Abstract

The main aim of this work is to design a compact Rectangular shaped Multislot patch antenna for Ultra Wide Band (UWB) and X band applications. The proposed antenna has a condensed size of 35*30*1.6mm3. The antenna consists of a rectangular patch with microstrip line feed etched on FR4-epoxy substrate with dielectric constant of 4.4. To improve the bandwidth, circular slots are made in patch and the ground plane. The proposed antenna achieves wide bandwidth of 12.7GHz (3.3-16 GHz) having four resonance frequency with good return loss and maximum gain of 9.64dBi. The antenna is designed, simulated and analyzed by using HFSS (High Frequency Structural Simulator). The charisma of this design is that it employs single patch that makes it easy to fabricate and cost-effective as well.
