Abstract
A new spiral square architecture antenna with unbalanced excitation was designed. Spiral antenna is formed by two arms, a ragged arousal in which one of the arms is powered by an inner conductor and the other is short-circuited with a ground plane by means of a cavity. The proposed antenna is able to generate a wide range of frequencies for transmission and reception of signals UWB to VSWR 2:1 without the need for adjustments to its parametersDownload
