This paper presents the design and results of a compact tapered U slot UWB printed monopole microstrip antenna. The planar, very small, thin UWB antenna fed by a single 50? microstrip line with truncated ground plane is excited by a coaxial SMA connector. The simulation was done using Ansoft High Frequency Structure Simulator (HFSS) software. Extensive investigations and parametric analysis is ...

An improved ultra-wideband (UWB) and high gain rectangular microstrip antenna is specifically designed in this paper using planar metamaterial based on double-ring resonators (DRR). The antenna has three doublering resonators (DRRs) etched on the metal patch, and a partial ground plane so that the impedance matching characteristics of the antenna are much better. The −10 dB impedance bandwidth ...

In this paper, both frequency and time domain performances of a new compact planar antenna for the ultrawideband (UWB) applications are fully investigated. The proposed antenna has the size of 12x18 mm2 providing a fractional bandwidth more than 128123% (3.057 GHz to 13.98 GHz, S11<-10 dB). The results show that the proposed antenna performances in term of wide bandwidth, small size, gain and r...

In this paper, we introduce a novel printed monopole antenna for ultra-wideband (UWB) applications. The antenna is composed of two overlapped circular disc monopoles with a finite ground plane and fed by a 50 microstrip line. The designed antenna operates over impedance bandwidth (2.9 to 11.6GHz) for return loss S Ω 11 < -10dB. The antenna also shows omni-directional radiation patterns and good...

An Ultra Wideband (UWB) microstrip diamond slotted patch antenna with enhanced bandwidth is presented in this paper. The proposed antenna is simulated in CST Microwave Studio and fabricated for measurements. Its simulated result displays impedance bandwidth from 3.28 GHz to 19.64 GHz, whereas the measured result displays the frequency region from 2.01 GHz to 18.67 GHz. The antenna complies with...

ELECT A new ultra-wideband (UWB) antenna integrated with a narrow-band (NB) antenna has been designed and fabricated. The UWB antenna consists of a U-shaped dielectric resonator fed by a microstrip line. In addition, the proposed structure integrates an NB slot with the same polarisation. The electromagnetic analysis is carried out by using two commercial software tools. To validate the propose...

─ In this study, we present an UltraWideband (UWB) monopole antenna with bandnotched function. The proposed antenna is fed by a microstrip line. By using two modified forkshaped slots in the ground plane, bandwidth is increased that provides a wide usable fractional bandwidth of more than 135% (2.82-15.63). In order to achieve band-rejected performance, a cross-ring slot was inserted at the squ...

This paper applies transmit antenna selection algorithms to spatial-temporal combining-based spatial multiplexing (SM) ultrawideband (UWB) systems. The employed criterion is based on the largest minimum output signal-to-noise ratio of the multiplexed streams. It is shown via simulations that the bit error rate (BER) performance of the SM UWB systems based on the two-dimensional Rake receiver is...

The design of UWB systems for consumer electronic application requires the integration of the antenna for aesthetical design reason. This paper discusses the influence of the integration on the performance of UWB antennas and the entire radio link. Investigations based on numerical simulations show that the antenna performance is drastically affected when the antenna is integrated into the chas...

The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
