ULTRAWIDEBAND-EMBEDDED MULTIBAND PLANAR MONOPOLE ANTENNA

In this letter, we present an ultrawideband (UWB)-embedded multiband planar monopole antenna. The proposed antenna is composed of a chopped semicircular radiator appended with a meander and a folded branch microstrip line. Owing to inclusion of the semicircular radiator, the antenna can have the UWB characteristic. Also, the meander and the folded-branch microstrip line guarantee low-frequency bands, including global system for mobile communication, digital communication system, personal communications service (PCS), United States personal communications service (US-PCS), wideband code division multiple access, bluetooth, and US-worldwide interoperability for microwave access. A high-frequency structure simulator was used to analyze the proposed antenna in the design process and to compare the simulation and experimental results. The bandwidth of the proposed antenna was measured for voltage standing wave ration less than 3. (c) 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1111-1115, 2014
