| Summary: | A multiband multiple-input multiple-output (MIMO)
antenna system consisting of two antenna elements has
been proposed for 4G USB dongle application. The
designed MIMO antenna system with a compact volume of
25 mm × 30 mm × 3.5 mm
operates in two zeroth-order resonance (ZOR) modes to
cover the LTE band 13 (746–787 MHz),
GSM850/900 (824–960 MHz), and LTE band 7
(2500–2690 MHz) simultaneously. A pair
of L-shaped parasitic strips and an etching slot on
the ground are employed to achieve good isolation
between two elements. Measurement results show that
proposed MIMO antenna system has total efficiency over
40% across the operation band and isolation less
than −8 dB at the lower band and
−16 dB at the upper band,
respectively. |
