Design and Characterization of Multiband and Broadband Printed Patch Antennas for Wireless Applications

Abstract

In the last decade, wireless communication systems have spread widely and become an essential tool in every days life. A tremendous increase in the demand for small Personal Mobile Devices (PMD) has been observed with wide model ranges and applications. A novel approach is presented to make compact multiband, broadband, ultra wideband (UWB), CP band microstrip patch antennas (MPAs), and array antenna with improved stable radiation patterns at a higher frequency for wire- less communication systems. The challenges with the fabrication and utilization of traditional MPA and array antenna designs at UWB frequency are solved by the method presented here. Also, UWB is rapidly improving as a high-data-rate wire- less communication technology. Like in regular wireless communication systems, an antenna is a very important part of UWB systems. But designing a UWB antenna is harder than designing a narrow-band antenna. A good UWB antenna should be able to work over the Federal Communications Commission’s (FCC) ultra-wide bandwidth at the same time, it must have good radiation properties across the entire frequency range.
