This paper prevents a wideband low noise amplifier worked in L band and S band using a new equalization structure. Usually, in order to design a wideband amplifier, we should use an equalization to compensate for inconsistencies in active component's gain response. Microstrip equalizer is always composed of microstrip transmission line coupled with microstrip resonators and resistance. It is known...
This paper discuss an ultra-wideband shielding materials, consisting of more than sixteen layers, where, metal wires periodically printing on it, an ordinary dielectric substrate. Depending on the FDTD (finite-different time-domain) method, we have calculated the field distribution and shielding effectiveness. We have studied how the number of layers and the number of the wire influence the shielding...
This paper illustrate the rapid design and debugging for a high restraint filter, by an example of a filter. we have designed a bandpass filter, which passband is 964MHz to 1029MHz, and at 960MHz the restraint is more than 40dB. The rapid methods include two parts, circuit synthesis and HFSS simulation. The way of debug the filter is by the delay and phase.
This paper prevents a new structure to construct a narrow band bandstop filter by combining stepped-impedance line with defected ground structure (DGS) resonator. This work use microstrip technology to provide a convenient way to connect with other microwave circuit. It has a sharp reject band, and the fractional bandwidth of 10dB cutoff is about 5%. This filter works in the center frequence of 14GHz,...
