Novel Low Pass Filters Using a Defected Microstrip Structure

In this article, the stop-band characteristics of a novel defected microstrip structure (DMS) are studied and its application to a low pass filter is proposed. The equivalent circuit model of the unit defected microstrip structure is used to explain th...
A novel defected microstrip structure (DMS), which behaves in a way similar to the known defected ground structure (DGS) unit cell, 1–10 is studied in this article. The unit DMS 3,4 is made by etching slots in the microstrip line, which then exhibits the property of rejecting microwaves at...

Accurate Simulation of an X-band Frequency Synthesizer

This article describes the simulation and design of an X-band frequency synthesizer that can be applied to a micro-satellite transmitter system. The effects of the sideband’s spurious noise on the adjacent channels and the phase noise in each component...
Today’s transmitters for earth imaging micro-satellite systems demand higher communication quality and higher data rates to be capable of transmitting pictures or data with an appropriate quality, a higher frequency of operation and more channels per unit bandwidth. Low power consumption and small size are also required for this...
