La formalitat dels conceptes del polĂtic i del dret en Carl Schmitt
Aquest treball pretĂ©n simplement mostrar un fragment inicial de la recerca que el seu autor estĂ duent a terme sobre alguns autors i temes relacionats amb les Ă rees de la filosofia i la teologia polĂtica. En ell, concretament, hom s'atansa a la qĂĽestiĂł de la formalitat dels conceptes schmittians del polĂtic i del dret, formulant temptativament la tesi que aquesta formalitat Ă©s essencialment polèmica i nomĂ©s aparentment buida de tot contingut material

Perturbation of the sierpinski antenna to allocate the operating bands
A scheme for modifying the spacing between the bands of the Sierpinski antenna is introduced. Experimental results of two novel designs of fractal antennas suggest that the fractal structure can be perturbed to enable the log-period to be changed while still maintaining the multiband behaviour of the antenna.Peer ReviewedPostprint (published version
Miniature Wideband stacked microstrip patch antenna based on the sierpinski fractal geometry
The main interest in the design of a miniature microstrip patch antenna (MPA) is its small size in conjunction with the well-known advantages of a MPA (cost, profile, weight). However there is a big constraint on the bandwidth limitation either in a miniature antenna or in a MPA. The proposed solution to overcome such problem is to couple a miniature parasitic resonator to the miniature active patch forming a wideband small stacked microstrip patch antenna.Peer ReviewedPostprint (published version
