Abstract
ABSTRACTThis article presents the design, fabrication, and characterization of a weakly coupled multibeam reflector antenna. To overcome the problems caused by tight coupling, the multibeam reflector antenna used Split Ring Resonators (SRRs) and stubs. The proposed antenna consists of one monopole antenna and four SRRs on top of a dielectric substrate, with a feeding connector at the bottom. The proposed multibeam reflector antenna was designed with an independent architecture to operate at 2.45 GHz. The beam steering is determined based on the switching status of SRRs. This switching methodology allows us for high transmission‐speed operations than the conventional multi‐input multi‐output antennas. In addition, larger amounts of data can be transmitted because of the radiation sum. Also, the proposed antenna did not need an isolator. The measurement results demonstrate that the proposed antenna exhibits beam‐steering and Mirror Image Pattern Pair capabilities successfully. © 2017 Wiley Periodicals, Inc.
