Advanced system integration excels as one of the key trends in wireless applications in the upcoming
decade. With the growing number of wireless mobile applications, there is a strong need for a more
efficient system partitioning in order to reduce the total silicon area that is used, and to increase the
flexibility and reuse (multimode or multistandard) of various integrated circuits.
This project aims to develop passive devices for implementing agile radio frequency (RF) transceiver
capacities in future radio communication products. We will focus specifically on the design of
reconfigurable and/or multiband passive devices, such as antennas and filters/duplexers, because they
are key elements in terms of footprint size and cost in a multi-standard system.
We will address the challenge at several stages of the design process by developing novel simulation
tools, characterization and modelling tecniques and advanced design techniques of reconfigurable
and/or multiband passive devices. This sistematized process will lead to manufacture several
demonstrators to evaluate the viability of the developed techniques.
The overall objectives of the project are:
1. Develop advanced synthesis and design techniques for high-selectivity BAW filters/duplexers
including new functionalities, such as single-ended to balanced conversion, multiband, multimode,
and tunability. Prototypes will be manufactured.
2. Develop new synthesis techniques to design optimum filter-antenna modules, multiband filters with
arbitrary bands and lossy filters techniques for tunable devices. Manufacture reconfigurable filters
to demonstrate the viability of the proposed techniques.
3. Develop large signal nonlinear models for tunable devices including self-heating effects and define
the required measurements to parameterize the models.
4. Design a filter to provide distortion-free ultrawideband performance in a wide angular range when
combined with an electrically small antenna. Assess its performance for short-range
5. Design and fabrication of wideband, multiband and electrically small antennas.
6. Design and fabrication of reconfigurable antennas for RFID applications and industrial environments.
7. Develop advanced electromagnetic simulation tools, based on Integral-Equation based frequency
domain methods, which allow the analysis of the problems described in this proposal by improving
the accuracy of the solutions, the efficiency in obtaining the solution or the well-posedness of the
matrices to be handled.
This proposal corresponds to a coordinated project involving four research teams from the Universidad
Autónoma de Barcelona (UAB), Universidad Politécnica de Cataluña (UPC), Centro de Investigaciones
Tecnológicas IKERLAN, and Centro de Estudios e Investigaciones Técnicas (CEIT). It intends to go a
step further from the previous coordinated project TEC2009-13897-C01/02 "Technology and Design
Techniques for the on Chip Integration of Microwave Front-ends (TD4CHIP)“, which was evaluated as
Outstanding (“muy satisfactorio“) by the MICINN. The primary objective of the preceding project was to
improve the integration and compaction of passive circuits that are part of microwave front-end
modules, while maintaining their high performance in terms of losses and linear behavior. In view of its
results and its very satisfactory evaluation, the present proposal is the natural evolution towards multistandard
transceivers using the most promising technologies studied in the previous project.
