Ionospheric disturbance is a major impediment to current communication systems with the signals propagating through the ionosphere. A signature of such disturbance when appearing in an ionogram, resulting from the ionosonde observation system, is known as spread-F. The spread-F statistics is therefore crucial to the design and operation of communication system. In this work, we analyze the equatorial...
Antennas which are used to transmit and receive UWB signals must be able to accomodate its large bandwidth. Moreover, the signals should not be distorted too much when they pass through the antennas. Therefore, the transfer function of antennas should be known for the performance evaluation. Conventionally, the authors measure the transfer function of the antenna by measuring the transmission coefficient...
Presently the communications technology is much progress and devices are likely to be used on body network. Education has been thought. This project studies patterns of ultra wideband for a broadband network on the body network. It is high speed data technology for study the impact of the human body. The vector network analyzer is used to measure and record the results. Those results are process by...
Wireless technology today are more advancement, especially technique use in communication and communication devices are likely to be closer on the more human. This research is impact of UWB Impulse radio with human body base on measurement data, this type of technology is a high-speed data transmission. To study the impact of the human body that affect the technology UWB, Using a vector network analyzer...
