Abstract: In this paper, a compact UWB antenna with band-notch characteristic is proposed. To realize the stop-band, the spoon-shaped slots are inserted in the pattern of planar monopole antenna. This antenna is operating in the UWB spectrum from 3.1 to 10.6 GHz and has the stop band from 4.8 GHz to 6.3 GHz where VSWR is higher than 3. This antenna is made by LTCC process and the size of this antenna is 15*15*1 mm3.

TL;DR: In this article, a coplanar waveguide (CPW) fed novel planar ultra-wideband antenna with a band-notch characteristic is presented, which consists of a rec- tangular metal radiation patch and a tapered arc-shaped ground plane.
Abstract: A coplanar waveguide (CPW) fed novel planar ultra-wideband antenna with a band-notch characteristic is presented. The proposed antenna consists of a rec- tangular metal radiation patch and a tapered arc-shaped ground plane. To achieve ultra wideband, three modifications are introduced, the first one is to remove a 90-degree fan angle on the upper corners of the patch, the second one is to shape the bottom of the patch into an arc, and the third modification is to remove a small fan angle on each side of the ground plane near the feeding line. Simulation results show that the proposed antenna operates over 3.0 to 23 GHz for VSWR < 2. By embedding a C-shaped slot in the radiating patch, a frequency band notch between the bandwidth of 5 to 6 GHz for Wireless LAN (WLAN) will be obtained. All simulations in this work were carried out by using the electromagnetic software Ansoft HFSS 11. Compared with the recently proposed antennas, this antenna has advantages in wide bandwidth, good band-notch characteristic, compact in size and easy design. Details of the proposed antenna are presented, and simulated results show that the antenna has stable radiation patterns and good gain flatness over its whole frequency band.

TL;DR: A coplanar-waveguide fed ultra-wideband (UWB) antenna with substrate-integrated waveguide (SIW) stop-band resonators is intro-duced for the 3-10 GHz band as discussed by the authors.
Abstract: A coplanar-waveguide fed ultra-wideband (UWB) antenna with substrate-integrated waveguide (SIW) stop-band resonators is intro- duced for the 3-10 GHz band. The symmetrically placed SIW cavities provide dual-stop-band characteristics due to their TE101 and TE102 res- onance modes. Thus, the entire UWB is divided into three pass-bands which cover the frequency ranges 4.23-4.62 GHz, 6.6-8.175 GHz, and 9.39-10.7 GHz. Measurements of a prototype show good agreement with simulation results with a minimum measured return loss of 9 dB in any of the three pass-bands. V C 2014 Wiley Periodicals, Inc.

TL;DR: In this article, the authors present a bird view for the beginners those work on reconfigurable MIMO antennas with band notch features and develop them to have a great insight about the available reconfigurability antennas.
Abstract: With the speedy evolution in the wireless communication systems, there is an extreme requirement for extraordinary data rate, high reliability, and good quality of transmission link. To aid these requirements, techniques involving Multiple-Input-Multiple-Output- (MIMO) antenna is one of the utmost promising implementations. Without surplus power requirement, it employs multiple radiators at both transmitting and receiving side that further improves the system capability and reliability. Strength of a signal and data throughput of wireless communication systems can be enhanced further by implementing a system which is reconfigurable with MIMO antenna. However, there can also be a common situation where there can be coexistence of all the wireless bands. Hence designing of UWB-MIMO is a challenging assignment and it turns into a more challenging task when the preference of selective band rejection is also integrated (i.e.) a method of introducing reconfigurability. This article gives a bird view for the beginners those work on reconfigurable MIMO antennas with band notch features and develops them to have a great insight about the available reconfigurable MIMO antennas. Further this type of review is not presented in the literature to our knowledge.

Abstract: A double-sided rounded bow-tie antenna (DSRBA) for ultrawideband (UWB) communication is proposed. The antenna covers the UWB spectrum from 3.1 to 10.6 GHz, and has return loss below -10 dB throughout the entire band. The antenna has also omnidirectional radiation characteristics and reasonable gain values over the same frequency band. Two different substrates, Rogers RO3006 and Liquid Crystal Polymer (LCP), are considered. Both materials have very low loss tangent. Results regarding return loss, far-field pattern, and gain are presented

TL;DR: In this article, a U-shaped metal-plate monopole antenna is proposed to provide a very wide operating bandwidth of larger than 7.6 GHz, which can easily cover the 3.1-10.6GHz UWB band.
Abstract: A novel, ultrawideband (UWB) monopole antenna suitable to be mounted on the printed circuit board (PCB) of a wireless, universal, serial-bus (USB) dongle as an internal antenna is presented. The proposed antenna in the study is a U-shaped, metal-plate monopole antenna, easily fabricated from bending a simple metal plate onto a foam base of a compact size of 6times11times20 mm3. The antenna mainly comprises a pair of wide-ended radiating arms and a bevel-feed transition. When the antenna is mounted at the top portion of the PCB, one end of the radiating arm is also short-circuited to the system ground plane. With the proposed antenna structure, which can provide a very wide operating bandwidth of larger than 7.6 GHz, the antenna impedance bandwidth can easily cover the 3.1-10.6 GHz UWB band. Details of the antenna design are described, and experimental results of the constructed prototypes are presented and discussed
