Reconfigurable beam reflectarray antenna for frequencies in the range of terahertz and millimeter waveThe reflectarray antenna consists of a flat array of phase-shifter cells (reflectarray) illuminated by a feeder, which produces an electronically reconfigurable collimated or shaped beam, where the cells (3b) consist of several stacked layers of conductive elements (4c, 4e, 4d, 4f) on a dielectric substrate (7c, 7d) alternated with layers of liquid crystal (5c, 5d) and a conductive plane (9). Applying bias voltages in the conducting elements, the dielectric constant of the liquid crystal varies producing a phase shift of the reflected field in each cell, allowing for a electronic beam scanning or reconfiguration. Including multiple layers of conductive elements and liquid crystal, improves the bandwidth and the performance of the beam scanning or reconfiguration. The antenna can be applied to observation satellites, communications and security systems.

Procedure and system for the passive location of wireless nodesA procedure for positioning wireless nodes under a passive approach, i.e., just listening to the radio medium has been developed. Thus, each regular location process run to locate a specific wireless node in the network yields to several nodes knowing their own position. Partners to further develop the system and/ or to establish commercial agreements with technical cooperation are sought.

New FFTH-PON Network for extended numbers of usersA new Passive-Optical-Network (PON) for Fiber-To-The-Home (FTTH) services has been developed in the frame of the National Research Project TEYDE. While current FTTH networks as GPON and EPON can reach a maximum of 32-64 users, the proposed PON can serve more than 4000 users, thanks to a new device for distributing the signal among the users that intelligently recycles the noise generated by other elements of the network. Partners to further develop the device and/or to establish license agreements with technical cooperation are sought.

A low-complexity and low-power receiver for wireless communicationsA superregenerative receiver for digital phase-modulated signals has been developed and patented. The technology described herein extends for the first time the conventional superregenerative receiver to be able to detect PSK signals with a minimum of additional circuitry. Taking advantage of both the lowcomplexity and low-power from superregenerative receivers and the more efficient power transmission achieved by PSK modulations. Partners to further develop the system and/or to establish commercial agreements along with technical cooperation are sought.

OPTICAL REMOTE NODE DEVICE AND SUPPORT EQUIPMENT FOR CONSTRUCTING AND EXTENDING FIBRE-OPTIC ACCESS NETWORKSThe Remote Node performs all-optical interfacing between a metropolitan ring and the access trees to the homes, thus enabling a transparent metro-access converged optical network. The device performs the functions of wavelength add&drop, ring protection and optical amplification with remote pumping. It is composed by a number of optical elements not requiring electrical power supply.
