An interlaced E-shaped antenna for LTE (Band-Class-13) handset applications

The long-term evolution (LTE) standard has attracted much interest due to its many advantages. Antenna design for the lower band of the LTE systems for mobile handsets faces challenges of the limited space and long wavelengths. An LTE smart mobile antenna is presented, and influences of various design parameters are investigated using the CST Microwave Suite. The antenna shape was then modified to obtain a bandwidth of (50) MHz centered at (767) MHz, and VSWR of 1.163. The antenna has compact size of 60×15×0.8mm3 (0.154×0.038×0.002 wavelengths at center frequency).
