Robotics &Vision lab (RVL) is mainly featured by the vision of robotic systems which sense and interact with the physical world. However, in the near-field region, absorption of radiation does affect the load on the transmitter.Īn antenna array is used to increase overall gain, provide diversity reception, cancel out interference, maneuver the array in a particular direction, gage the direction of arrival of incoming signals, and to maximize the Signal to Interference plus Noise Ratio (SINR) In the far-field region of an antenna, radiated power decreases as the square of distance, and absorption of the radiation does not feed back to the transmitter. The antenna pattern is the response of the antenna to a plane wave incident from a given direction or the relative power density of the wave transmitted by the antenna in a given direction. Impedance matching, HF Radio communication system, To achieve optimum performance level Without proper matching, the antenna becomes a chokepoint of performance due to reduced range, increased power consumption and impaired data transfer. Impedance matching ensures maximum efficiency.
