Dual notched USlots triple band tunable rectangular microstrip antenna

Abstract

This article presents a novel design and development of dual-notched U slots rectangular microstrip antenna for quad band tunable operation. The antenna operates between 3.45 and 8.75 GHz at four different frequency bands. The middle two bands merge into a single band by changing the width of U slot on the patch. This change will also effect in tuning the three bands on either side of the frequency spectrum without changing the nature of linearly polarized broadside radiation characteristics. The proposed antenna gives a peak gain of 1.52 dB. The experimental and simulated results are in good agreement with each other. A design concept of the antenna is given and experimental results are presented and discussed. This antenna may find applications in WLAN, WiMax, and the fourth generation mobile communication systems. (C) 2012 Wiley Periodicals, Inc.
