Study of a miniaturized circular patch diversity antenna for mobile terminals

The demand on portable and user-friendly wireless communication devices has geared up accordingly which necessitates optimal miniaturised built-in antenna for mobile terminals. This paper presents a design of a miniaturized circular microstrip L-probe wideband patch antenna for achieving diversity operation at mobile terminals. The design is optimised to cover the UMTS, LTE and WLAN. A prototype is fabricated, and its s-parameters and radiation paters are measured to verify the design.
