Switchable triple band-notched UWB antenna modelling for interference rejection from dual WiMAX bands and satellite C-band service

A Conformal Frequency Reconfigurable Antenna with Multiband and Wideband Characteristics

“…The presented work was compared with the state-of-the-art works reported in literature, as summarized in Table 1 . It can be observed that few works [ 17 , 18 , 27 ] are reconfigurable with good impedance bandwidth and significant gain; however, these designs have been employed on rigid substrates, which limit their effectiveness for various wireless communication applications. Other works presented in [ 25 , 26 , 28 , 29 , 30 ], demonstrate the advantages of reconfigurability and flexibility; however, these antenna structures either have larger dimensions or exhibit narrow bandwidth and low gain as compared to the proposed antenna.…”

“…In particular, a frequency reconfigurable antenna is beneficial for various applications. Frequency reconfigurability can be achieved by using electrical switches [ 9 , 10 , 11 ], varactor diodes [ 12 , 13 , 14 , 15 ], p-i-n diodes [ 16 , 17 , 18 , 19 ], and radio-frequency micro-electromechanical systems (RF-MEMS) [ 20 , 21 , 22 ]. The electric switching technique has the advantage of lower voltage requirements, whereas RF-MEMS provide higher switching time.…”

“…The configurable operations using p-i-n diodes have also been introduced. [12][13][14][15][16][17] In Boudaghi et al, 14 a monopole antenna was introduced that could create five adjustable states using a switchable gap on the ground. In Medkour et al, 15 a single-layer antenna was introduced that covers the UWB band and has two adjustable band-notches.…”

“…The reconfigurable notch‐band can be controlled by RF switches, such as p‐i‐n diodes, RF MEMS, and MOSFETs. The configurable operations using p‐i‐n diodes have also been introduced 12–17 . In Boudaghi et al, 14 a monopole antenna was introduced that could create five adjustable states using a switchable gap on the ground.…”

“…In Medkour et al, 15 a single‐layer antenna was introduced that covers the UWB band and has two adjustable band‐notches. In Shome and Khan 16 and Chen et al, 17 p‐i‐n diodes were used to create a band‐notch. In Kalteh, 18 a ring patch antenna was also introduced that has a band‐notch performance using diodes.…”
