Antennas

Basic Description

Antennas sense an electromagnetic field and convert it to an electrical signal. There are many antennas in a typical automobile including antennas for AM and FM radio reception, GPS navigation, Bluetooth communications, cellular telephone communications, and possibly DSRC communication. Antennas are also an integral part of radar distance sensors.

Connected vehicles technologies require the car to open an increasing number of communication links. Thus, the design and placement of the antennas in a car is becoming a significant concern. Multi-band and reconfigurable antenna systems capable of transmitting and receiving in different frequency bands are likely to play an increasingly important role.
