Integrated broadband planar monopole antenna with additional frequency bands

Abstract

In this article, an integrated broadband planar monopole antenna with extra frequency bands is presented. The proposed antenna consists of a simple square shaped planar. The center part of the plate can be removed with negligible effect on reflection coefficient. To improve the impedance matching of the planar antenna, the lower corner of the antenna is removed. Also, the higher cut‐off frequency is enhanced by an additional strip at the top corner of the plate. By inserting additional strips in the path of the notched part of the plate, integrated broadband antenna with extra bands can be attained which leads to dual‐ and triple‐band antenna. The additional bands cover 1.71–1.88 (DCS) and 2.4–2.48 (WLAN). Simulation and measurement results of the proposed antenna agree well and show good performance for multiband behavior. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1923–1926, 2014
