“…5(b), the surface currents are concentrated more on L 1 stub, and the direction is opposite to the remaining patch currents that lead to a notch band at WiMAX band. The stub length is chosen equal to λ g /4 that act as a short circuit and creates a notch band at WiMAX [26], [31]. Due to this reason the currents in patch are opposite the patch currents.…”

A triple-notch band planar ultra-wideband (UWB) antenna is proposed for wireless body area networks (WBANs) to suppress unwanted signals of conventional narrow band communication technologies. These notch bands are WiMAX (3.3-3.8 GHz), WLAN (5.1-5.825 GHz), and X-band downlink satellite communication systems (7.25-7.75 GHz). A complementary split ring resonator slot and two L-shaped stubs are introduced on an elliptical-shaped radiating patch to obtain UWB coverage from 2.9 to 12 GHz with three notch bands. The overall antenna structure is fabricated on FR4 substrate with a size of 12 mm×19 mm which provides a size reduction of more than 42% with respect to recent literature. The simulated and measured results indicate that the proposed antenna is a good candidate for WBAN applications.

“…Further, three notches can also be obtained by modifying radiator [17] with several slots. U-shaped type slots in ground and arc shaped slots [18] in the radiators are used to obtain notches in radiators to obtain triple band notches. Radiator and ground plane [19] etched with c-shaped slots obtain triple notches.…”

A triple band notch MIMO/Diversity antenna using Inductance Boosted Compact Electromagnetic Band Gap (IB-CEBG) cells is presented in this paper. For obtaining compactness in the conventional EBG cell, spiral shaped defects are introduced. The proposed antenna obtains triple band notches in WiMAX (3.3-3.6 GHz), WLAN (5-6 GHz), and the X-band satellite communication (7.2-8.4 GHz) bands. IB-CEBG cells exhibits miniaturization of approximately 46% for WiMAX band, 50% for WLAN band and 48% for X-band Satellite communication band, compared to conventional EBG cells. To enhance the isolation among all four compact UWB monopoles, rectangular slots in the ground plane and parasitic decoupling arrangement are utilised. Further, a stepped structure with an angular separation of 90 • is incorporated with individual monopoles to reduce mutual coupling effects. Stepped structure also helps in the better impedance matching by incrementing the path length. The results show that the magnitude of transmission coefficient is greater than 15 dB in between the ports of proposed antenna elements. Envelope Correlation Coefficient is less than 0.5, which lies in tolerable limits for Ultra-Wide band (UWB) frequency range. It has been noticed that notched frequency is dependent on IB-CEBG cell parameters. The proposed antenna is fabricated using an FR-4 substrate with overall dimensions of 58 × 90 × 1.6 mm 3 .

“…In [18], a triple band notched antenna is obtained using C-shaped slots in the radiator and ground plane. In [19], a triple band notched antenna is obtained using an arcshaped slot in the radiator and a U-shaped slot in the ground plane. Problem with these approaches is that all approaches are antenna design specific and give poor control on notch location and width.…”

Abstract-A MIMO/Diversity antenna with triple notch characteristics is proposed in this article. The proposed antenna has triple notches in the WiMAX band (3.3-3.6 GHz), WLAN band (5-6 GHz), and X-band satellite communication (7.2-8.4 GHz) band. Defected Ground Compact Electromagnetic Band Gap (DG-CEBG) is a design used to accomplish band notches. Defected ground planes are utilised so as to achieve compactness in conventional EBG structures. The proposed WiMAX band, WLAN band, and X-band satellite communication band DG-CEBG structures show a compactness of around 46%, 50%, and 48%, respectively, over a conventional EBG structure. In these structures, decoupling strips and a slotted ground plane are used to enhance the isolation between two closely spaced UWB monopoles. The individual monopoles are 90 • angularly separated with a stepped structure which helps to reduce mutual coupling and also contributes towards impedance matching by increasing the current path length. |S 21 | or mutual coupling is found to be less than 15 dB over the whole UWB frequency range. The Envelope Correlation Coefficient (≤ 0.5) is within the acceptable limits over the whole UWB frequency range. Notched frequency depends on the parameters of DG-CEBG structures; when there is a change in these parameters notch frequency is also changed. A low cost FR-4 substrate with thickness (h) = 1.6 mm, permittivity (ε) = 4.4 and loss tangent (δ) = 0.02 is used for the proposed antenna, and it has a compact size of 58 × 45 × 1.6 mm 3 .
