摘要：
A compact, multiband, shorted monopole antenna is presented for ultraslim mobile handsets. The proposed antenna is formed by a simple structure of three radiating strips of different length namely, /4 C-shaped radiating strip, 3/8 meandered line radiating strip, and a /4 shorting strip. Which results in proposed antenna that covers GSM850/900/1800/1900/UMTS/Wi-Fi/LTE2300/2500/WiMAX bands with respect to -6 dB impedance bandwidth. The measured peak realized gain is observed between 1.2 and 4.2 dBi while simulated total radiation efficiency is between 60 to 93% in the operating bands. The proposed antenna is investigated in free space as well as in actual mobile environment consisting of mobile plastic housing along with large metallic display screen and battery. Specific absorption rate computation is also carried out on human head phantom in vicinity of the proposed antenna and obtained well below the specified limit. The parametric analysis is also carried out to understand the effect of the shape parameters of the antenna. (c) 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1459-1466, 2015
