DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR ... The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, designed on the bottom of the Duroid substrate. The mean length of the slot circumference is approximately 3 λs/2 at the frequency of 5.8 GHz Broadband Slotted Coaxial Broadcast Antenna Technology Broadband Slotted Coaxial Broadcast Antenna Technology John L. Schadler Director of Antenna Development Dielectric L.L.C. Summary Slotted coaxial antennas have many advantages over traditional broadband panel antennas including much smaller size and wind load, higher reliability and a greater degree of azimuth and elevation pattern US4547779A - Annular slot antenna - Google Patents This invention deals generally with annular slot antenna structures and, in particular, with microstrip annular slot antenna structures providing vertically polarized radiation in a monopole or annular slot pattern. Low profile conformal microstrip radio frequency antenna structures are, in general, now well known in the art. Mutual coupling reduction between elements of UWB MIMO ...

Radar Basics - Slot Antennas Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz.Jacques Babinet (1794 - 1872) was a French physicist and mathematician, formulated the theorem that similar diffraction patterns are produced by two complementary screens (Babinet's... Single-Feed Circularly Polarized Annular Slot Antenna… A novel dual-broadband circularly polarized folded slot antenna with single-feed is presented.The proposed antenna consists of two folded annular slots. By adjusting the asymmetric widths of the two slots, circularly polarized radiation can be achieved in two different bands. Review Paper for Broadband CPW-Fed T-Shape Slot Antenna -…
