A meandered line-PIFA antenna for LTE (Band-Class-13) handset applications

The long-term evolution (LTE) standard has attracted much interest because it offers many advantages. Antenna designers for the lower band of the LTE700 band for mobile handsets have to compromise between the limited space in the handset and long wavelengths implied by frequency of operation. An antenna with meandered line-PIFA combination is proposed as a solution for the above challenge. The influences of various design parameters are investigated using the CST Microwave Studio Suite. The antenna shape was then optimized to obtain a -6dB bandwidth of (58) MHz centered at (765) MHz. The antenna offers a second band at 2.16GHz for other applications. The antenna has compact size of 65×110×1.6mm3 (0.165×0.28×0.004 wavelengths at the center frequency of the lower band).
