A novel compact ultrawideband biconical antenna with the impedance bandwidth of 200–965 MHz for VSWR less than 2.35 is proposed. Two metal disks and cylinders are loaded around a traditional biconical antenna, which can form two magnetic dipoles. The broadband impedance matching, miniaturization, and omnidirectional radiation patterns are achieved through the combination of the biconical antenna and...
In this paper, a compact dual-polarized printed dipole antenna with wide band is proposed. This design employs two techniques to improve its performances. Exponential curve lines are employed to improve the impedance matching. Horizontal slots are used to miniaturize the surface area of this antenna. The dimension of this single polarization antenna is 63mm × 47 mm. The dual-polarized printed dipole...
In the cloud computing era, the goal of data center network is not only to interconnect a large number of servers, but also to provide low latency and high bandwidth. A new 2-layer architecture, C-tree, is proposed for cloud computing in this paper. It is a flat topology, in which the horizontal traffic's latency is obviously lower than in traditional three-layer architectures. Also, C-tree can provide...
