A switched-beam antenna for cellular communication
Wireless communication has created a continuing demand for increased
bandwidth and better quality of services. Smart antenna arrays are one of the ways to
accommodate this demand which can provide numerous benefits to service provider
and the customer. Switched-beam antenna was chosen for this project due to its easier
implementation and lower cost compared to adaptive array. Switched-beam antenna is
one of smart antenna technique which comprises a number of predefined beams. The
control system switches among the beams that provide the maximum signal response.
Through the investigation and study on this system, found that, the 1200 sectorization
with three monopole antenna elements suited for prototype construction. The initial
stage to design this system is by using MA TLAB simulation to identify the antenna
characteristic and the parameters involved. The second stage is about the construction
of the prototype switched-beam antenna used to measure the antenna gain and relative
power level which displayed using CASSY program
MIMO radar system as improvement mechanism for agriculture applications
This paper looks at MIMO radar system as improvement mechanism for agriculture applications
A preliminary study towards the implementation of MIMO radar system for agriculture applications
The revolution of MIMO radar system has the potential to be applied in many areas of applications such as in agriculture sector. It is inspired from MIMO system in telecommunications and uses multiple antennas to observe the different aspect of targets, hence produce high resolution radar image
