Abstract

Future aeronautical and astronautical communities have to prepare for space communications with extraordinary innovative technologies for deeper space research beyond our solar system. One of the aspects is the design and development of suitable antenna systems for space communications. In recent times the micro strip antennas are widely used in microwave and millimetre wave applications starting from satellite to mobile communication hand held sets due to its low profile, light weight and other advantages of VLSI technologies which are promising for further research for new technologies with new avenues in the form of Nano particle strip antenna systems.

The aim of this theoretical concepts research paper is to propose and discuss design considerations for nano strip antenna systems which are required to transmit and receive directly from satellites and beyond our solar system. In this paper an attempt is made to present and discuss the design considerations and implications of designing the nano strip antenna systems for space applications. In this research work requirements of power, gain, bandwidth, radiation pattern and so on for nano strip antenna design and development for space applications are proposed and discussed.

Abstract

Technologies have advanced rapidly in the field of digital signal processing due to advances made in high speed, low cost digital integrated chips. These technologies have further stimulated ever increasing use of signal representation in digital form for purposes of transmission, measurement, control and storage. Design of digital filters especially adaptive or semi adaptive is the necessity of the hour for SAR applications. The aim of this research work is to design and evaluate the performance of 380-400 KHz Bartlett, Blackman and Chebyshev digital semi adaptive filters. XILINX and MATLAB software are used for designing of these filters. As part of practical research work these designs were translated using FPGA hardware SPARTAN-3E kit. Blackman and Chebyshev filters designed using software and hardware were tested by a sinusoidal test signal of 381 KHz along with noise and the filtered output signals are presented. These designs were optimized, analyzed, compared and evaluated keeping the sampling frequency at 5 MHz for 64 orders.
