“…When the capacitance value is increased to 4.15 pF, the upper-end of the rejected band is increased from 5.89 to 6.2 GHz, while its lower end at around 5.01 GHz remains the same. Although this phenomenon is slightly different to [25], whereby a distinct variation is observed, this result provides yet another method to fine tune the bandwidth of the rejected band.…”

“…Lastly, during the investigation on prototype B, a question was raised if a tunable band rejection function can be achieved if the two loaded Pin-diodes are replaced by varactor diodes as studied in [25]. Hence, an experiment was conducted by employing two varactor diodes (model: SMV-1232) that will provide a variable capacitance values from 0.72 to 4.15 pF by tuning the voltage across it from 15 to 0 volts.…”

“…[5] In order to overcome this problem, various UWB antennas have been designed to omit the undesirable bands causing interference with other systems. In this way, different kinds of techniques have been utilized to reach the desirable performance of UWB systems without any distortion from other narrow-band devices [2,6].…”

“…Therefore, the antenna filtering capability can be further improved by making this band-notched behaviour switchable [131] [132]. Since the existence of interfering systems depends on the antenna environment, the filtering function exhibited by planar monopoles with fixed band-notched behaviour might not be necessary in some cases.…”
