The Public University of Navarre’s (UPNA) telecommunications engineering graduate, Israel Arnedo Gil has suggested a new technique for microwave filters design with the use of synthesis tools.
These tools were tested in radar signal processing, space sector and ultra wide band (UWB) technology applications successfully. Gil has completed a PhD thesis involving novel methods for the production of microwave devices based on the mode-coupling concept.
Space applications if microwaves require an optimal technique for communication between satellites and Earth stations for ensuring high-quality signals. In this context, a robust microwave filter design has been suggested, which is capable of offering enhancements over the presently used techniques from cost and service points of view.
The tools recommended for wide band radar applications facilitate the design of an optimal device for processing high-speed analog signals, resulting in expanding the practical application areas for this technology.
UWB technology has evolved from wireless communications and offers additional flexibility for service and usage. UWB is also vital for the implementation of enhanced security systems such as radio monitoring and under-earth detection applications such as antipersonnel mines and buried earthquake victim detection, making the need for optimal design of receptors and emitters extremely important. Arnedo has collaborated with the Institute National de la Recherche Scientifique for designing two devices that are expected to pave the way for meeting the above requirements.
Microwave filters are utilized to control the time and energy required for transmitting between two points in a system. Gil’s research work has facilitated the improvement of particular applications and award of a global patent for exploration rights.
Millimetric and microwaves are used for operating wireless, radar, mobile telephony, microwave oven and satellite communications systems. They are also utilized for generation, processing and sensing electromagnetic signals that are in the 1 GHz to 300 GHz range. They are used in diverse applications that include information transmission through space links and terrestrial microwave links, radar, and high sensitivity receptors used in the field of radio astronomy.
These applications need microwave filters for their operation for permitting only particular electromagnetic waves to pass. Arnedo’s thesis aims to improve particular microwave applications by improving the tools utilized for designing microwave filters.
