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...
A novel mobile terminal antenna covering the low LTE and GSM850/900 communication standards (i.e 700-960MHz) is proposed. The two-port antenna is composed of two coupling elements manufactured on a plastic piece using a laser direct structuring technique. To obtain a high port-to-port isolation between the two feeds, a neutralisation technique...

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....

In this article, we present a new wideband hybrid coupler for millimeter‐wave applications realized in the BiCMOS9MW 130‐nm process from STMicroelectronics. The fabrication of two slightly different couplers demonstrates the wideband performance associated with miniaturized size, thanks to the use of meandered transmission lines and lumped...
During recent years, various research teams have developed 60-GHz chipset solutions, using both BiCMOS and advanced CMOS technologies. However, for the 60-GHz market to flourish, not only low-cost RFICs are required, but also cheap antennas and package solutions. In order to address these two last issues, we present the design of a Tx-Rx...

With fast-growing demand for high-speed mobile communications and highly saturated spectral usage below 10GHz, mm-Wave frequency bands are emerging as the key playground for future high-data-rate wireless standards. Recent years have witnessed vast technology development on V-band (60GHz) Wireless Personal Area Networks (WPAN) and E-band...

In this paper, we present a new symmetric feeding technique for a broadband planar antenna-array. The antenna consists of four linear series-fed arrays of four microstrip patches positioned in parallel. To avoid any beam tilt during frequency scanning, one side of the array is supplied by a 0° signal whereas the same 180° out-of-phase signal...
In this paper, we present several antenna-array topologies for quadrature spatial combining: In-phase and Quadrature signals are not anymore combined at the circuit level but rather spatially in free space. To demonstrate the feasibility of this concept, an organic module with two 4×1 antenna-arrays is fabricated and measured in V-band....
A differential feeding technique for a broadband planar antenna-array is presented. The antenna structure is composed of four parallel linear series-fed arrays of four microstrip patches. To cancel the beam tilt versus frequency, one side of the array is fed with in-phase signal, whereas the same out-of-phase signal feeds the opposite side of...
