SINGLE ANTENNA RADAR SENSOR USING PATCH ANTENNA

摘要

PURPOSE: A radar sensor using the patch antenna of the single antenna structure does not use the outside element such as the hybrid coupler and circulator. The radar sensor can be embodied as the single antenna. CONSTITUTION: An oscillator(510) erupts in the specific frequency. A power divider(520) distributes the sine wave signal created in oscillator. Part of the sinusoidal wave the signal divided through the power divider is inputted to the transmitting end port(530). A patch antenna radiates part of the sinusoidal wave signal in object. The reception end port(550) receives a message the signal reflected to from the patch antenna in object.
