Algunos aspectos de la presencia del «L’Inno a Satana» de Giosuè Carducci en la literatura española

[ES] La presencia de Carducci en la literatura española fue intensa y ha sido bien estudiada en sus aspectos generales. Sin embargo, este estudio analiza ese tipo de literatura carducciana, representado por el Inno a Satana, que suscitó un cierto rechazo por la carga de impiedad que podía deducirse del mismo título, analizando cómo personajes relevantes de la literatura española como Juan Valera y Miguel de Unamuno interpretan el poema, lo sitúan y lo ponderan en su justa medida, minimizando las características de ataque a la moralidad imperante en la época y valorándolo como un ejercicio literario bien construido y como arranque de la poderosa obra carducciana.[EN] Carducci’s presence in Spanish literature was very intense and had been very studied in its general aspects. However, this study analyzes that type of Carducci’s literature, represented by Inno a Satana, that suscited a kind of refusal for the impiety load that it could be deduced from the title, analyzing how relevant personages of the Spanish literature, such as Juan Valera or Miguel de Unamuno, interpret the poem, situated it and consider it in its fair misure, minimizing the characteristics of attack to the morality prevailing in those years and valuing it as a well constructed literary exercise and as the beginning of the powerful Carducci’s work

Lumped-Element Balun for UHF UWB Printed Balanced Antennas

A semi-lumped balun transformer for UHF and ultrawideband (UWB) dipole antennas is presented in this paper. The proposed structure is based on two asymmetric filters that also transform the variable antenna impedance into the desired source impedance. These asymmetric filters make use of a binomial impedance transformer in each filter section. The asymmetric filters (one low pass filter, LPF, and other high pass filter, HPF) allow the balun bandwidth to be increased while the binomial transformer matches the variable balanced dipole impedance. In this way the ripple in the balun response due to the variation of the UWB dipole impedance is reduced. A balun for a UHF and UWB dipole antenna working from 220 to 820 MHz (bandwidth of 4:1) has been achieved with losses lower than 1 dB. These types of baluns are particularly useful in the low microwave frequency band
