Band-notched ultra-wideband circular slot antenna with inverted C-shaped parasitic strip

Design and Analysis of a Compact Elliptical Dual Band-Notched Uwb Antenna Using Escsrrs

“…Then, stable realized gain with good band-notched characteristics and omnidirectional radiation patterns is desired. Therefore, various simple shapes like rectangular, circular, elliptical UWB and slot antennas with and without single/dual band-notched functions are reported and demonstrated in the literature [3]- [16].The planar circular and elliptical UWB antenna [3]- [5], circular and elliptical slot UWB antenna [6]- [7], band-notched circular slot UWB antenna using inverted C-shaped parasitic stub [8], heartshaped UWB antenna using U-shaped slot for band-notched UWB applications [9], band-notched semi-elliptic slot UWB antenna [10], dual band-notched UWB antenna [11], dual band-notched UWB antenna using defected ground structure (DGS) and split-ring resonator (SRR) [12], dual bandnotched compact UWB antenna [13], a CPW-fed dual bandnotched hexagonal open slot antenna [14], dual bandnotched UWB antenna using complementary SRR [15], and electromagnetically coupled elliptical UWB antenna using parasitic element [16] are reported and presented.…”

A novel UWB slot antenna with reconfigurable rejection bands

“…Many techniques also used to introduce notch band for rejecting the interference in the UWB slot antennas. It is done either by inserting half wavelength slits, stripes in the tuning stub [3], or inserting square ring resonator in the tuning stub [4], or with complementary split ring resonator [5], or inserting strip in the slot [6]. All the above methods are used for rejecting a fixed band of frequencies.…”

A NOVEL MAPLE-LEAF SHAPED UWB ANTENNA WITH A 5.0-6.0 GHz BAND-NOTCH CHARACTERISTIC

“…It requires an antenna of small size, wide impedance bandwidth of 3.1-10.6 GHz, omni-directional radiation patterns, and stable gain. Various types of planar UWB antennas have been developed for UWB applications [2][3][4][5][6][7][8][9][10]. However, there are several narrowband communication systems operating below 10 GHz and may cause interference with UWB systems such as wireless local area network (WLAN) systems operating at 5.15-5.825 GHz frequency band.…”

“…However, there are several narrowband communication systems operating below 10 GHz and may cause interference with UWB systems such as wireless local area network (WLAN) systems operating at 5.15-5.825 GHz frequency band. To solve this problem, many UWB antennas have been proposed for achieving band-notched characteristic [8][9][10][11]. Some techniques are based on embedding a thin slot in the radiating patch, i.e., π-shaped slot [8], or using parasitic strips, i.e., inverted C-shaped parasitic strip [9].…”
