“…In the proposed structure, at the notched frequency, the surface currents concentrated on the folded stubs and the opposite ground plane are oppositely directed. As a result, the resultant radiation fields cancel out and high attenuation near the rejected frequency is achieved [4]. Fig.…”

“…Nevertheless the antennas have the common deficiency of large size. In [4], by inserting shorted quarter-wavelength resonator strips which are connected to the ground plane via holes, the antenna achieves two notched bands with limited size. It is a pity that the antenna has a low rejection level at the notched bands (less than −3 dB).…”

Abstract:A novel planar antenna with WiMAX and WLAN bandnotched characteristics is presented for ultra-wideband (UWB) applications. The UWB antenna consists of a staircase-shaped radiating element, a microstrip feedline and a modified ground plane. To realize WiMAX band-notched characteristic, a pair of hook-shaped slots is etched on the radiating element. Two folded stubs extending from the ground plane are used to reject the WLAN band for the first time. The antenna meets a bandwidth from 2.95 to 11.6 GHz, with two notchedbands of 3.25-3.95 GHz (WiMAX) and 5.00-6.50 GHz (WLAN), respectively. Measured and simulated results of the impedance bandwidth, gain, and radiation patterns are presented and discussed.

“…For instance, in [12] a single notch is created in UWB antenna by utilizing an open loop resonator on the back side of the substrate. A couple of nested C-shaped stubs are used in [13] to generate multiple notch bands. In [14] crescent-shaped resonators are designed on the ground plane of the antenna and shorted with radiation element through via holes to generate multiple notches.…”

Abstract-A sharply rejected dual notch band UWB monopole antenna is presented in this paper. The proposed antenna consists of maple leaf shaped radiating element, a 50 Ω microstrip feed line and truncated ground plane. The proposed antenna shows the UWB operation in the frequency range (1.7 GHz-11.1 GHz) with VSWR < 2 except the notch bands and two band notches centered at 4.3 GHz and 7.7 GHz. The band notches are achieved by introducing a meandered slot in the radiating element and U-shaped slot in feed line. The substrate used for designing of UWB antenna is low loss Rogers 5880 having relative permittivity of 2.2. The novelty of the proposed antenna is its shape and ability to support UWB bandwidth requirements, and it also rejects two bands to avoid possible interference with existing communication system. Good agreement between the simulated and measured results is observed. The proposed antenna has good gain and efficiency at pass bands.

“…In [14], A-shaped antenna was proposed that covered a bandwidth from 2.9 GHz to 11.5 GHz. Some other reported shapes of the patch with wide slot are circle [15] square [16] and deformed hexagon [17]. In this communication, we present a circularly slotted elliptical patch antenna with an elliptical notch in ground for L-band and S-band application, and the proposed antenna is investigated numerically and experimentally.…”

Abstract-A circular slotted elliptical patch antenna with an elliptical notch in ground for L-band and S-band application is presented. The proposed antenna consists of an elliptical patch with a circular notch on the top layer of a substrate, and a wide elliptical slot and an elliptical notch with two symmetrical slots on the bottom layer of the same substrate. The proposed antenna was fabricated on an FR-4 substrate (tan(δ)= 0.02,ε r = 4.3) with the thickness of 1.6 mm, and it was excited by coaxial feed joined with microstrip line through via. The proposed antenna exhibited the bandwidth of 102.58% from 1.32 GHz to 4.1 Hz for |S 11 | < −10 dB. Surface current distribution and radiation pattern at resonating frequencies 1.71, 2.28, 3.03 and 3.84 GHz were analyzed. Evolution of the antenna and effect of parameters were also studied to know the behavior of the antenna.
