How does a slot antenna work?

The slot antenna is compared to its complementary dipole to illustrate that the radiation patterns produced by a slot antenna cut into an infinitely large metal

Slot antennas are an about λ2 elongated slot, cut in a conductive plate , and excited in the center This slot behaves

slot machines harrahs cherokee Directional radiation pattern: Slot antennas produce a directional radiation pattern, which is ideal for point-to-point communication systems
