According to the simulation results, in every antenna case, the microwave power distribution was nearly ellipsoidal around the slot, and it shows the highest

As illustrated in Figure 7-3, a slot in an infinite plane is equivalent to a dipole of the same dimensions In practice, a sheet much bigger than  Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz They are often used in navigation
