Beamforming is a signal processing technique. It has been studied in many areas such as radar, sonar, seismology and wireless communications, to name but a few. It can be used for a myriad of purposes, such as detecting the presence of a signal, estimating the direction of arrival, and enhancing a desired signal from its measurements corrupted by noise, competing sources and reverberation. Actually, Beamforming has been adopted by the audio research society, mostly to separate or extract speech for noisy environment.

This paper deals with the collision avoidance radar based antenna performance characteristics. This antenna can be placed inside the vehicle and it receives the signals from the base station and warns the driver accordingly. If any accident occurs to that vehicle, then that information is also passes to substation for help. The proposed antenna is designed on liquid crystal substrate and all its output parameters are simulated and presented in this work.

This volume, derived from the Handbook of Engineering Electromagnetics (2004), is intended as a desk reference for the fundamentals of engineering electromagnetics. Because electromagnetics provides the underpinnings for many technological fields such as wireless communications, fiber optics, microwave engineering, radar, electromagnetic compatibility, material science, and biomedicine, there is a great deal of interest and need for training in the concepts of engineering electromagnetics.

The term ‘microwaves’ is used for those wavelengths measured in centimetres roughly from 1 m. to 0.1 cm or the bands of frequencies between 300 MHz to 300 GHz. Microwaves are most popularly used in point to point communication, TV broadcasting via satellites and in RADAR systems. Besides these, they are also being used in industrial, biomedical, chemical and in scientific research applications. The latest wide acceptance of the microwave application is as “microwave heating” in synthesizing various compounds (organic and inorganic) in research laboratories as well as in industries....

Ultra wideband (UWB) communication systems are characterized by high data rates, low cost, multipath immunity, and low power transmission. They are widely used in wireless communications, networking, radar, imaging, and positioning systems. In 2002, the Federal Communication Commission (FCC) legalized low power UWB emission between 3.1 GHz and 10.6 GHz for indoor communication devices stimulating many novel UWB applications such as personal area networks (PANs), accurate tracking and location, safety and homeland security....

Today, the development and use of microwave (3-30 GHz) and millimeter wave (30-300 GHz) band is being actively promoted. Microwave has been used extensively since the Second World War when the sources were based on vacuum devices. Microwaves are presently playing a vital role in RADAR, land and satellite based communication and also have wide civilian and defence applications. Two typical areas of application of millimeter-wave are information communication and remote sensing.
