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 ... (PDF) Design and Development of a 2.4 GHz Slot Antenna The slot antenna was designed from the intuition of Babinet's principle, that a horizontal electric dipole in free space is the dual of a vertical slot and will have the same radiation pattern as ...

Dipole antenna - Wikipedia In radio and telecommunications a dipole antenna or doublet is the simplest and most widely used class of antenna. The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary electric dipole with a radiating structure supporting a line current so energized that the current has only one node at each end. US6414647B1 - Slender omni-directional, broad-band, high ... The present invention is directed toward a dual linear or circular polarized antenna comprised of two orthogonally linearly polarized radiative elements. More specifically, the present invention is for a slender slot-dipole antenna, where the slot and the dipole are located in the same physical structure. Magnetoelectric Dipole Antennas With Dual Open-Ended Slot ... Designs of novel magnetoelectric dipole antennas excited by dual open-ended slots for both single and dual linear polarizations are presented in this paper.
