	Abstract:A bandgap reference, which is based on Brokaw bandgap reference and can supply 4.75 v and 1.186 v, is introduced. The low frequency PSR (power-supply rejection) of the 4.75 v output voltage is -133 dB, and the smallest PSR in the frequency range of 1Hz to 1 GHz occurs at 14 MHz, which is -20 dB. And the temperature coefficient of 4.75 v is 45 ppm/℃ in the temperature range of -50℃ to 150℃.

	Abstract:In this paper, a novel compact microstrip low-pass filter with nonuniform microstrip resonant cells is designed. The proposed filter is formed by cascading the four nonuniform 1-D microstrip photonic bandgap (PBG) cells, while each unit cell was designed with different cutoff frequency etched on the 50Ω microstrip line. The demonstration low-pass filter with the cutoff frequency of 2.2GHz is designed, fabricated and measured. The measurement results show that the band rejection level is more than 20dB from 2.8GHz to 10GHz, the insertion is less than 2dB, and the length of it is 5.6cm. Compared with the conventional filter, this method overcomes the problems of narrow stop-band, low harmonic suppression and has an advantage of miniature circuit size. Moreover, it does not need to consider the impedance matching.

	Electrics, Communication and Autocontrol Technology 06 March 2009
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Normally, both currents and voltages are needed to solve parameters of differential equations of Maxwellian Circuits. In this paper, a technique of voltage cancellation is applied to the theory of Maxwellian Circuits for solving linear wire antennas and scatterers. Its advantage is that only currents are used to seek parameters of differential equations, voiding the process of solving voltages with currents and simplifying calculation. The computational results show that the technique is reliable.

	Abstract:With the current and future requirements of space-borne microwave and millimetric wave instruments, particularly for earth observation, there has been considerable research effort put into large reflector antenna system worldwide. Dichroic are key components in the design of large reflector antenna systems. But the measurement performance of dichroic is usually different from simulation result, this problems will degrade the performance of the whole antenna systems very seriously. This paper presents the analysis of fabrication errors of two-layers dichroic for quasi-optical network, The Inter-layer Separation Distance (ISD) and the Unit cell Aligning Error (UAE) was modelled and analysised. The results show that The ISD and UAE will degrade the performance of the dichroic obviously, and the dichroic of rectangular elements is very sensitive to the UAE on X direction rather than that of the Y direction.

	Abstract:In this paper, the method mixed potential integral equation (MPIE) combined with half rooftop basis function is used to analysis the long-wire antenna with matched loading terminations. MPIE is a kind of integral equations in Method of Moment (MOM) and can effectively deal with models with terminal loads. The contribution of this method is that we can take proper measures to the boundaries of the model by using the half basis function, which allows the current to flow across the edges. All of the elements in MoM impedance matrix, only the elements in the first and second rows need calculating for the structure of straight line according to the principle of reciprocity and symmetry. The results of current, voltage along the line and the radiation field calculated by this method agree well with the results of theoretical value and transmission-line theory(TL).
