Abstract
A hepta-band covering GSM850/900/1800/1900/ UMTS/LTE2300/LTE2500 handset antenna array is presented. The antenna array consists of two symmetric antenna elements, A T-shaped protruded ground(TP) and three slots. The antenna element consists of a feed strip and two radiation strips (RS1, RS2), which only occupies a planar size of 15×25 mm2 and generates dual-mode resonances at λ/8 and λ/4. The three slots and T-shaped protruded ground are utilized to reduce mutual coupling. Different slots can adjust different frequency bands independently. The working mechanism of the three slots is analyzed based on S-parameters and surface current distributions. The measured S11 and S12 are lower than −6 dB and -15 dB in the working bands, respectively. The radiation patterns and diversity performance are presented.
