A novel multiple-input-multiple-output (MIMO) dual-antenna system covering the low LTE700 and GSM850/900 communication standards is proposed for mobile terminals. The two-port antenna system is composed of two 3-D coupling elements, placed on the vertices of the short corner of a rectangular FR4 substrate. This rectangular shape emulates the...

A novel approach for antenna designs covering the LTE frequency bands in a mobile handheld terminal is proposed. The concept consists of a low-band antenna operating in the 700-960MHz band, associated with a high-band antenna operating from 1700 to 2700MHz. The two antennas are separately fed...
A feasibility study of 4G cellular antennas operating in the LTE, GSM, DCS, PCS, and WLAN2400 standards for wirelessly connected eyewear is presented. The target bands are 700-960 MHz and 1.7-2.7 GHz. The antenna designs are capacitive coupling element types, with simple layout printed on one side of the printed circuit board (PCB) substrate....

Two antenna designs with tunable matching circuits suitable for 4G mobile terminals are presented. SPDT MEMS switches and tunable capacitors as active components are evaluated in those two different antenna topologies, in scope of the Artemos European project. The target bands include the 4G communication bands, i.e. 700-960MHz as the low-band...

An antenna-system covering the LTE700 and GSM850/900 standards is presented. The proposed structure has been designed to fit in generic handheld devices. It has been manufactured using Laser Direct Structuring technology on a plastic piece. The principal design challenge for the antenna is to cover the target band with a short ground plane...
