In this letter, we present a concentric annular-ring microstrip antenna that covers the bands of Galileo (E5a, E5b, E1, E2, L1), GPS (L1, L2, L5), and GLONASS (L1, L3). This microstrip antenna is fed by four apertures that improve the coupling. Broad band phase shifters and Wilkinson power combiners are used to generate the required circular polarization.
Conference Paper: Research activities of Spanish antenna groups[Show abstract] [Hide abstract]
ABSTRACT: When we look at the history of electricity and electromagnetism in Spain we discover that the most important Spanish researchers are generally out of the official institutions or stable research groups until the 20th century  . In the 20th century most of the scientific research is done in stable research institutions and universities and the most important electromagnetism research centres in Spain are located in the Faculty of Physics of the most important universities, the National Scientific Research Council (CSIC) and the School for Telecommunication Engineering created in 1923. But the greatest impulse of research in the antenna and radiowave propagation field is done after 1960 reaching the first national URSI conference in 1980. After that year, the relation between groups and the number of research groups is continuously growing and the relation to industry is also increasing. When Spain joins the European research organizations (COST, ERC...) and the European Union in 1985 the research support experience a fast growing and the participation in the European research structures.Antennas and Propagation (ISAP), 2012 International Symposium on; 01/2012

ABSTRACT: In this letter, we present the design of a concentric annular ring slot antenna with right-hand circular polarization. Two concentric rings have been etched in the ground plane to generate a dual-band response. A broadband feeding network and a thicker substrate below the slots have been used to improve the axial-ratio bandwidth and gain. The proposed antenna covers the bands of the positioning systems GPS and Galileo. Experimental results show a 3-dB axial-ratio bandwidth for the lower and upper band of 19.2% and 18%, respectively. The measured gain is higher than 4 dB in both bands.IEEE Antennas and Wireless Propagation Letters 12/2012; 11:705-707. DOI:10.1109/LAWP.2012.2205365 · 1.58 Impact Factor

ABSTRACT: An analytical model is presented to investigate the performances of an annular-ring patch etched on a two layered dielectric substrate, by using a full-wave spectral domain technique in conjunction with the complex resistive boundary condition. Galerkin's method and Parseval's theorem are used to obtain the resonant frequency and bandwidth. Numerical results for the air gap tuning effect on the operating frequency and bandwidth of the high Tc superconducting microstrip antenna are presented. The analysis is validated by comparing the results with a specific example in the literature.International Journal of Microwave and Wireless Technologies 01/2013; 5(5):611-619.
