Radial line slot antenna design

Radial Line Slot Antennas | SpringerLink A radial line slot antenna (RLSA) is a circularly polarized high efficiency planar array. Two types of RLSAs, a single-layered and a double-layered one, were released commercially for 12 GHz band direct broadcast satellite (DBS) reception.

Designs and Experiments of a Novel Radial Line Slot … A radial line slot antenna (RLSA) is a nonresonant multimode waveguide slotted array. To improve the power handing capacity, we design a radial line slow wave structure which replaces a traditional dielectric sheet. At the same time, the structure of the radiator unit is redesigned and optimised. Radiation properties of PIFA | 3. EBG-PIFA ANTENNA … One of the current constraints on antenna design for small hand-held devices such as mobile phones, personal digital assistants (PDAs), and wireless wearable computers is the limitation of design space, particularly for some internal antennas such as printed dipoles, meander- line, antennas and planar...
