A novel approach for low mutual coupling and ultra-compact Two Port MIMO antenna development for UWB wireless application.

In this paper, a novel MIMO antenna operating in the UWB frequency band is presented. The proposed new antenna shape is derived from the conventional circular ring patch antenna having a partial ground plane. An array of three Quad-G Shaped Metamaterial structures was used between the antenna elements of the two-port MIMO antenna to expand the bandwidth in the lower frequency band of UWB application (below 5.

A compact dual-band Dolly-shaped antenna with parasitic elements for automotive radar and 5G applications.

In this paper, a compact dual-band Dolly-shaped antenna (DBDSA), resonating at 23.52 GHz and 28.39 GHz, is proposed for automotive radar, 5G, and Industrial, Scientific, and Medical (ISM) applications.

A novel quadband ultra miniaturized planar antenna with metallic vias and defected ground structure for portable devices.

A novel heart-shaped monopole antenna used in wireless portable communication devices is proposed and discussed in this paper. The antenna has a radiant patch surface area of 28.504 mm, the physical size of 15 × 12.
