Abstract-In this paper, a coplanar waveguide fed (CPW-Fed) ultrawideband (UWB) antenna with dual band-notched characteristics is proposed. Two symmetrical slots are etched from the ground plane to achieve the notched band at 5.5 GHz. The other notched band at 3.5 GHz is obtained by etching a split ring slot in the radiator. The simulation and measurement show that the proposed antenna achieves an impedance bandwidth of 3.1-10.6 GHz with VSWR < 2, except in the bands of 3.2-3.8 GHz and 4.8-6.2 GHz. A nearly omnidirectional radiation pattern and stable gain with variation less than 3 dB are also observed except in the two notched bands. Moreover, time-domain characteristics of the antenna are analyzed and discussed as well.

“…Many band-notched antenna designs are achieved by cutting slots in the radiator [2,3]. To microstrip-fed UWB antennas, the band-notched characteristics can also be implemented by adding a stepped impedance resonator (SIR) or a split ring resonator (SRR) on the feed line [4,5] or cutting slots in the ground plane [6].…”

“…In order to minimize the interference between the narrow-band system and UWB system, the UWB antennas with band-notch characteristics have been introduced. Many band-notch antennas are achieved by cutting slots in the radiator [10,11], and some other UWB band-rejection antennas are also implemented by etching slots on the ground [12]. Moreover, controlling the resonant frequency of the antenna is an an efficient way to achieve bandrejection feature [13].…”

Abstract-Two different types of band-notch UWB-MIMO antennas are proposed in this paper. The filtering effect can be achieved by integrating slot resonators to a UWB antenna. Both of the proposed antennas have very compact size and are smaller than most of the other band-notch UWB-MIMO antennas. The ultra-wideband is achieved by etching stepped slots on the ground. The band-notch characteristic can greatly reduce the potential interference between the UWB and WIMAX/WLAN system. Our proposed antennas can also possess a wide bandwidth from 3 GHz to 11 GHz with |S 11 | < −10 dB. Some effective measures have been taken and illustrated to reduce the isolation. Measurements demonstrate that the mutual coupling between the antenna elements is good enough for a MIMO system. Their stable radiation patterns are simulated, designed and measured successfully. The good performance and compact size make the antennas good candidates for UWB applications.

“…With advances in wireless systems, the need for broadening frequency bandwidth and sharing multi-frequency bands has increased. Several conventional antennas, such as helical [2], horn [3], monopole [4][5][6], wide slot [7,8], and electric-magnetic dipole [9], are also available for wide impedance bandwidth applications. Additionally, multiband resonance can be achieved by adding a parasitic line or a shorted parasitic element to the main monopole patch [10,11].…”

Abstract-A microstrip-fed planar monopole antenna consisting of an inverted-L monopole and a square parasitic element extending directly from ground plane to obtain wideband operation covering Bluetooth/ISM, 2.5 GHz WiMAX, 3.5 GHz WiMAX and 5.2/5.8 GHz WLAN bands is presented. The proposed antenna employs a shorted parasitic element to improve the bandwidth. The return loss of the suggested antenna geometry was calculated by a commercial HFSS 9 simulator and the results are compared with measured return loss, which shows a good agreement between them. Details of the proposed antenna designs and experimental results of the constructed prototypes are presented.
