Antenna performance characteristics

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.

Modern communication systems require radio frequency and microwave signals for the wireless transmission of information. These systems employ oscillators, mixers, ®lters, and ampli®ers to generate and process various kinds of signals. The transmitter communicates with the receiver via antennas placed on each side. Electrical noise associated with the systems and the channel affects the performance. A system designer needs to know about the channel characteristics and system noise in order to estimate the required power levels....
