Practical multi-band antenna for 3G and 4G mobile services

This paper presents a compact antenna design based on PIFA configuration with multi-band features. The present design operates over the lower and upper bands of LTE700/2600MHz, together with the existing standard of GSM1900MHz. An approach of size miniaturization and triple band characteristics was applied through the embedded slot over the radiator surface. The antenna occupies a small volume of 13.5×50×7mm
³
, which is mounted over the ground plane with dimensions of 50×100mm
²
. Moreover, two identical antennas are integrated within the home device, where their results are checked and compared with the standalone version of the antenna.
