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.
Keywords-elliptical patch antenna; parasitic superstrate; The paper is organized as follows: In section 2, the detailed design of the antenna will be explained ranging from the elliptical design, the slots, and the connection between slots, the cylindrical patches and the dimensions of the ground the antenna consists of dielectric FR4 with an ... A reconfigurable radial line slot array (RLSA) antenna for ... A reconfigurable beam shape and broadside radiation pattern microstrip antenna is introduced in this paper. The antenna's radiating surface is designed using a radial line slot array (RLSA) arrangement, which is fed from an aperture coupled structure.

A wide beam radio frequency (RF) antenna includes a waveguide and one or more electrically conductive protrusions. The waveguide has at least one electrically conductive interior wall surface, a boresight defined by a longitudinal axis, and an aperture plane, transverse to the longitudinal axis, disposed at a distal end of the waveguide.
