“…However, the existing wireless networks such as C-band (4.0 ∼ 8.0 GHz) WLAN signals, and Xband (8.0 ∼ 12.0 GHz) satellite communication systems (XSCS) signals can interfere with UWB systems, thus compact UWB monopole antennas with multiple notched-bands are emergently required to reject these unwanted interfering signals [6][7][8][9][10]. To achieve desired band-notched performance, slots such as U-shaped and V-shaped ones are usually inserted on the initial UWB monopole antenna in [7] and [8]; however, only one notched band is created.…”

“…To achieve desired band-notched performance, slots such as U-shaped and V-shaped ones are usually inserted on the initial UWB monopole antenna in [7] and [8]; however, only one notched band is created. In [9] and [10], two notched bands can be introduced; however, considering that other services exist within the UWB band, wideband antennas with dual notch-bands are insufficient. Very few UWB antennas having quad notched bands have been reported [11]; however, the proposed structure is difficult to fabricate.…”

Abstract-In this paper, a novel planar monopole ultra-wideband (UWB) antenna with quad notched bands is investigated. The proposed antenna is composed of a circular-shaped radiating element, a 50 Ω microstrip feed line, a quad-mode stepped impedance resonator (SIR), and a partially truncated ground plane. By coupling a quad-mode SIR with an additional outer line beside the microstrip feedline, bandrejected filtering properties around C-band (5.2/5.8 GHz) WLAN bands, and X-band (8.5/10.5 GHz) satellite communication bands are generated. The measurement of voltage standing wave ratio (VSWR) is in agreement with simulation. The results show that the proposed antenna not only retains an ultrawide bandwidth but also owns quad band-rejections capability. The UWB antenna demonstrates omnidirectional radiation patterns across nearly the whole operating bandwidth that is suitable for UWB applications.

Abstract-In this paper we develop an empirical approach to the design of Ultra Wideband (UWB) antennas employing the Inverse Parabolic Step Sequence (IPSS). The relationships developed can be used to miniaturize the antenna and achieve a good impedance match over the UWB bandwidth. The overall aim of this process is to give a good starting point for detailed numerical optimizations. We will illustrate the use of these formulae in three different designs of IPSSbased antennas. A low loss duroid substrate of loss tangent, tan δ, 0.0009, low relative permittivity 2.2 and thickness 1.575 mm is used to simulate these planar monopole antennas in Ansoft High Frequency Structure Simulator (HFSS).

“…Therefore, to reduce the EM interference between the UWB and these bands, dual band notch filters in UWB systems are necessary. Recently, several UWB antennas with band-notch function have been reported [2][3][4][5][6][7][8][9][10][11]. But most of the proposed antennas have only one band-notched characteristic at 5.5 GHz [2][3][4][5].…”

“…But most of the proposed antennas have only one band-notched characteristic at 5.5 GHz [2][3][4][5]. Some UWB antennas with dual band stops have been proposed [6,7]. Both of them are small in size and broadband: one is 24.5×30 mm in size, 3-11 GHz impedance bandwidth [6], and the other is 26 × 30 mm in size, 2.8-11 GHz impedance bandwidth [7].…”

Abstract-A novel and compact planar ultra-wideband wide-slot antenna with dual band-notched function is proposed. The method of creating dual band-notch function is unique from traditional ones. By embedding a U-shaped parasitic strip and a pair of T-shaped stubs in the wide slot, dual bandstops around 3.5 GHz and 5.5 GHz can be obtained. The measured results demonstrate that the proposed antenna, with a compact dimension of 20 × 32.5 mm, has a large bandwidth over the frequency band from 2.5 to 11.7 GHz with voltage standing wave ratio (VSWR) less than 2, except the bandwidths of 3.3 ∼ 3.7 GHz for WIMAX and 5 ∼ 6 GHz for WLAN. In addition, the radiation pattern has an excellent omni-directional characteristic in H-plane and a typical monopole-like pattern in E-plane.
