Abstract:

For the working frequency of LTE（2.57~2.62 GHz）, based on the rectangular microstrip patch antenna, a novel
miniaturized loading slot microstrip patch antenna through opening four curved slits on the patch and loading two wide band 0.75 mm
square ring metal sheet at 1 mm above the patch has been obtained. And, the microstrip patch antenna has been modeled and
simulated by using the Ansoft's HFSS 3D electromagnetic analysis software. Then, the size, the S-parameter diagram, the pattern and
the VSWR of the slot antenna and the novel loading slot antenna have been compared. The simulation results show that the novel
loading slot microstrip patch antenna can achieve the miniaturization without compromising the performance of the antenna, and it's
has good practical value.

Key words: microstrip antenna, loading slot, miniaturization, LTE
