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 .

“…The Federal Communications Commission allocated the frequency band 3.1-10. 6 GHz for the UWB services in 2002 [1,2]. However, over the designated UWB frequency band, there are existing WiMAX and WLAN operating bands such as the 3.5 GHz (3400-3690 MHz), the 5.2 GHz (5150-5350 MHz) and 5.8 GHz (5725-5825 MHz) bands that UWB devices may cause interference to [3,4].…”

Abstract-A compact ultrawideband (UWB) monopole antenna with two U-shaped slots for WLAN and WiMAX dual band-notched functions is proposed and experimentally studied. The proposed antenna with the size of 28 mm × 24 mm × 1.6 mm is excited by a 50 Ω microstrip feed line. The band-notch functions are realized by loading two approximate half-wavelength U-shaped slots which change the current distribution on the Y-shaped patch. The obtained results show that the designed antenna has an impedance bandwidth of 2.95 GHz-12 GHz for S 11 ≤ −10 dB, except two frequency stop-bands of 332 GHz-3.98 GHz for WiMAX and 4.81 GHz-6.68 GHz for WLAN. The antenna has successfully fabricated and measured. The return loss, band-notched characteristic, radiation patterns and peak gains are presented

“…To avoid potential interference with existing wireless systems, a filter with band rejection characteristics is connected to the UWB antenna to achieve a notch function at the interfering frequency band. Recently, many UWB antennas with different bandstop filter designs have been widely discussed [7][8][9][10].…”

“…Gao et al [8] used a parasitic slots in the defected ground to stop radiation at the same frequency. A pi-shaped [9] or arc-shaped slot [10] in the radiating element have been used to obtain a band stop filter around the frequency of 5.8 GHz. Hong et al [11] introduced a hybrid technique for having band notch ability by using a complex parasitic element in the radiator and a modified defected ground to obtain the band rejection in the middle of UWB range.…”

Abstract-Two microstrip fed ultra-wideband (UWB) antennas with different band rejection techniques are presented in this paper. The designed antennas consist of a defected ground plane with an elliptical slot and two different radiator shapes. The first design is composed of a half circular ring radiator element while the second one uses a crescent shaped radiator. The radiators are fed by a 50 Ω microstrip line with a tapered microstrip transition to ensure good impedance matching. The calculated impedance bandwidth of the proposed antenna ranges from 3 GHz to 14 GHz with relatively stable radiation patterns. To achieve band-notch characteristic in the 5.0-6.0 GHz WLAN frequency band, two different techniques have been implemented. The first technique uses a C-shaped slot etched in the ground plane while the other one uses another C-shaped slot in the feed line.
