A compact printed ultra-wideband (UWB) monopole antenna with triple band-notched characteristics is presented. The first rejected band (3.3-3.6 GHz) for the WiMAX system is achieved by etching a split semicircular resonator (SSR) on the radiating element. Meanwhile, by adding two capacitively loaded loops(CLLs) close to the micro-strip feed line, the other two band-notched properties in the lower WLAN (5.15-5.35 GHz) and higher WLAN (5.725-5.825 GHz) bands are obtained. The size of antenna is 34 × 27 mm2. The measured results are roughly consistent with the simulated. The time domain characteristics are also analyzed. The results show that the proposed antenna has broadband matched impedance characteristics, stable radiation patterns, compressed notched-band gain as well as high time domain fidelity.

This paper presents the design and realization of a low insertion loss and high isolation Ka-band single-pole single-throw switch (SPST). This kind of switch is based on unilateral fin-line using four beam lead PIN diodes in parallel. The 3D EM simulation results demonstrated that, from 33 GHz to 37 GHz, the insertion loss of the switch is less than 0.5 dB while the isolation is greater than 32 dB. The measured value of the insertion loss is found to be less than 1.5 dB while the isolation is greater than 26 dB, which are in good agreement with the simulated results.

During the processing of Cloud platform it will generate a large amount of energy consumption. so how to improve energy efficiency become increasingly important. This paper presents a scheduling strategy which is based on the genetic algorithm for Cloud computing energy optimal. First, we adopt queuing network for system modeling and prove that the energy consumption of Cloud computing system is determined by the task scheduling probability. In order to obtain minimum energy consumption, genetic algorithms based on optimal reservation selection is use to optimize the dispatch probability. Simulation results show that this method is feasible to optimize energy consumption of cloud computing system.

A simple ultra-wideband (UWB) suspended stripline (SSL) bandpass filter based on the tubular filter structure is presented in this letter. In this design, the equivalent circuit of the proposed filter is considered as the tubular bandpass filter circuit. Then, the proposed filter could be realized by quasi-lumped elements using SSL easily. In the passband from 3.1 to 10.6 GHz, insertion loss is better than 0.5 dB, return loss is higher than 19 dB and the group delay variation is less than 0.7 ns. A good agreement between the simulation and measurement was observed.

A double-ridged TEM horn antenna, which was designed to be excited by the first derivative Gaussian pulse with central frequency 318 MHz, has been simulated to be well focused by the 10-layer traditional Luneburg lens. The metamaterial is introduced to construct an equivalent and isometric lens for the sake of cost and convenience. The effect of the modified lens is similar with the traditional.

A circularly polarized (CP) Microstrip Yagi array antenna (MSYA) is designed in order to achieve high front-to-back ratio R(F/B) and wide beamwidth radiation pattern. Two coaxial feeds with same magnitude and different phase is used to excite the antenna. Parametric studies are carried out to investigate the effects of some key geometrical sizes on the antenna's performance. The overlapped band that |Γ| ≤ -10 dB and AR ≤ 3 dB is wide enough. The R(F/B) of the CP antenna is more than 15 dB and the antenna has wide beamwidth over the spatial range including 0° ≤ θ ≤ 90° in vertical plane and more than 90° in horizontal plane.

The amplifier small signal gain exhibits >5 dB from 140 GHz-165 GHz. The peak gain is 11 dB at 140 GHz. This is the first time reported InP DHBT MMIC amplifier operating in D-band employing TFM in china. The total size of this 3-stage amplifier is only 1.04 mm×0.88 mm.
