1. A detection device for detecting an object under test, and comprising:
a radar module;
a waveguide element, coupled to the radar module; and
a first antenna element, disposed on the waveguide element;
wherein the radar module generates a first electromagnetic incident wave, and the first antenna element transmits the first electromagnetic incident wave toward the object;
wherein the first antenna element receives a first electromagnetic reflection wave from the object, and the radar module processes the first electromagnetic reflection wave;
wherein the first electromagnetic incident wave and the first electromagnetic reflection wave are propagated through the waveguide element;
wherein the detection device further comprises:
a second antenna element, disposed on the waveguide element;
wherein the radar module generates a second electromagnetic incident wave, and the second antenna element transmits the second electromagnetic incident wave toward the object;
wherein the second antenna element receives a second electromagnetic reflection wave from the object, and the radar module processes the second electromagnetic reflection wave.
