“…According to the literature, antennas used in CR systems can be divided into two categories [8], the one-and the two-port structures. The first category consists of using one antenna that can act as a UWB or narrowband, depending on the requested task [9]- [11]. While the second category consists of using an antenna system composed of two antennas [12]- [14], one for sensing and the other for communication task.…”

“…Also, in what's coming, bandpass and bandstop modes are used in the same way as in [8,10]. Bandpass mode designates a mode where the resonator acts as a bandpass filter, passing frequencies corresponding to roughly λ/2 and blocking the remaining frequencies.…”

“…The frequency reconfiguration usually consists in translating the operating band [2], creating new bands [3][4][5], but an important proportion of them consists in switching between a wideband mode and one of its sub-bands [6][7][8][9]. This last category of reconfigurable antennas is of particular interest for the proposed context as they allow varying the operating bandwidth.…”

“…Some work on reconfigurable Vivaldi antennas has been reported in [5]- [7]. In [5], two rings are introduced to a Vivaldi antenna to obtain narrowband reconfiguration, however the gain that can be achieved is low, only up to 5.93 dBi.…”
