A Broadband and High-Gain Metamaterial Microstrip Antenna

A braod bandwidth and high gain rectangular patch antenna was specifically designed in this paper using planar-patterned metamaterial concepts. Based on an ordinary patch antenna, the antenna has isolated triangle gaps and crossed strip-line gaps etched on the metal patch and ground plane, respectively. Demonstrated to have left-handed characteristics, the patterned metal patch and finite groun...

A High Gain Rectangular Microstrip Patch Antenna Using “Different C Patterns” Metamaterial Design in L-Band

Design of rectangular microstrip patch antenna loaded with “different C patterns” left-handed metamaterial structure has been proposed. The proposed metamaterial structure is designed at a height of 3.2 mm from the ground plane for L-band (1 GHz-2 GHz) applications. The most interesting feature of the design is the ability of enhancing the gain and total efficiency of the antenna without effect...

Design and Fabrication of Plasma Array Antenna with Beam Forming

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...
