A compact printed planar ultra-wideband antenna with dual band-notched is proposed. The proposed antenna consists of a rectangular radiating patch and a modified partial ground plane. Two rectangular parasitic strips are placed below the substrate to achieve dual band-notched characteristics. The measured results show that the proposed antenna achieved a(More)
A new design of dual band compact microstrip antenna is proposed for Ku-band applications. Dual band is achieved using three pairs of thin slits from the sides of a rectangular patch and feeding with a microstrip feedline. The antenna has a compact structure and the total size is 9.50mm by 10mm by 0.254mm. The result shows that the return loss of(More)
The peak to Average Ratio (PAR) or peak to average power ratio (PAPR) is a major drawback of most the multicarrier communications systems. In Orthogonal Frequency Division Multiplexing (OFDM), the PAPR is around 12–13 dB. Also in the Code Division Multiple Access (CDMA), the PAPR is appeared. By combining these two systems (CDMA and OFDM), a good(More)
A printed circular ring antenna for UWB application is proposed in this paper. The antenna structure is composed of a circular ring patch and a partial ground plane. The proposed antenna has a total size of 39 &#x00D7; 40 mm<sup>2</sup>. The measurement shows that the antenna has an impedance bandwidth (VSWR&#x2264; 2) of 9.54 GHz (2.54 to 12.08 GHz). A(More)
This paper presents a negative index metamaterial incorporated UWB antenna with an integration of complementary SRR (split-ring resonator) and CLS (capacitive loaded strip) unit cells for microwave imaging sensor applications. This metamaterial UWB antenna sensor consists of four unit cells along one axis, where each unit cell incorporates a complementary(More)
—A new compact ultrawideband (UWB) patch antenna based on the resonance mechanism of a composite right/left-handed (CRLH) transmission line (TL) is proposed. The radiating element of the antenna is made from three left-handed (LH) metamaterial (MTM) unit cells placed along one axis, where each unit cell combines a modified split-ring resonator (SRR)(More)
The main objective of Radio Frequency Identification systems is to provide fast identification for tagged objects. However, there is always a chance of collision, when tags transmit their data to the reader simultaneously. Collision is a time-consuming event that reduces the performance of RFID systems. Consequently, several anti-collision algorithms have(More)
Intercell interference is one of the most challenging issues in femtocell deployment under the coverage of existing macrocell. Allocation of resources between femtocell and macrocell is essential to counter the effects of interference in dense femtocell networks. Advances in resource management strategies have improved the control mechanism for interference(More)
