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...

Hybrid Broadband 60-GHz Double Negative Metamaterial High Gain Antenna

This paper proposes a double negative metamaterial surface as a superstrate for a multilayer cylindrical dielectric resonator antenna (MCDRA). The aim is to achieve a broadband and high gain Electromagnetic Band Gap (EBG) antenna that can be used in harsh propagation areas to satisfy all the requirements for the 60GHz wireless communications offering a bandwidth of 7GHz in the unlicensed ISM ba...

Development of Low Profile Substrate Integrated Waveguide Horn Antenna with Improved Gain

In this paper a new low profile Substrate Integrated Waveguide (SIW) probe-fed H-plane horn antenna structure with improved gain is proposed. The proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...
