Waveguide Slot Array Antennas | SpringerLink Figure 15 shows the equivalent circuit of the array antenna with the traveling-wave excitation. The slot antennas are numbered from the end to the feed. The designed excitation amplitude of the n-th slot is given as a n. The normalized conductance to be determined of the n-th slot is g n. Radar Basics - Slot Antennas Slot Antenna. 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 radar usually as an array fed by a waveguide. But also older large phased array antennas used the principle because the slot radiators are a very inexpensive way for frequency scanning arrays. . Slot antennas are an about λ/2 elongated ...
