Five prototypes developed by Alexander Martinez Ros with a flat and flexible technology have multiple functionality, from tracking to obstacles in automotive RFID, through data transmission at high speed
The School of Telecommunications at the Polytechnic University of Cartagena (UPCT) has strengthened its expertise in designing new antennas with reading the thesis Alejandro Javier Martínez Ros, he developed during his doctoral research five different prototypes with multiple applications.
The research director, José Luis Gómez-Tornero, defined as "holographic antennas, which can concentrate the electromagnetic energy in three dimensions and flexibly" defines the teacher UPCT.
In the thesis entitled "Analysis and Synthesis wave device in planar technology leakage 'Martinez Ros antennas versatile designs, which can freely control the radiation pattern independently changing both the amplitude and phase emission, and integrability total, having a thickness of only one millimeter and be of flexible material.
The result are prototypes with multiple uses.
For example, functioning as radar to detect obstacles, useful work to assist in parking or landing vehicles and adapted to curved spaces, since the radius of curvature can be corrected by adjusting the pointing angle.
Other possible future uses are in the field of medicine, by microwave hyperthermia treatments with potential application in cancer, concentrating the radiation emitted at a single point, with near-field antennas developed by the researcher, who are also useful for intrusion detection and RFID.
"As technology low cost, small size, can be used in logistic processes to find the location of the products," says the author of the thesis.
Other prototypes allow radiation vertically point to point or separation channels broadcast different frequency bands via a multiplexer system communications.
"The key is the independent control of the amplitude and phase, which allows us, for example, create zero radiation at certain points," says Martinez Ros.
"The designs are scalable to many frequencies, enabling data transmission at high speeds," he adds.
The antennas, which were manufactured and tested in Belfast Queen's University by the researcher, are made with Teflon substrate surrounded by metal.
Research has generated eight publications in international journals, and eight in national magazines and submitting articles in fourteen conferences.
In one, held in Florida, Martinez Ros was a finalist for the best paper of young researchers, and the International Scientific Radio Union gave a second prize at its congress in 2012.
