چکیده
The paper proposes a high gain, metamaterial based super wideband (SWB) antenna. SWB antenna has two inverted U slots which are responsible for notches at 3.5 GHz and 5.5 frequencies. A flower-shaped slot is etched from the radiator to obtain characteristics. dimensions of 30×35 ×1.5 mm3 with FR4 substrate. frequency bandwidth 3.1 - 15 S11 < -10dB. unit cell designed simulated permittivity permeability This shows negative refractive index in band 2.4 8 8.2 9 GHz. 3×3 array cells used as superstrate improvement gain fabricated prototype measured 3.1-15 notched bands experimental results line each other.

متن کاملA Millimeter-Wave Wideband High-Gain Antenna Based on the Fabry-Perot Resonator Antenna Concept
A compact millimeter-wave (MMW) wideband high-gain antenna is proposed and implemented. The development is based on the design principle of wideband Fabry-Perot resonator antennas (FPRAs). The antenna consists of triple-layer dielectric slabs and a PEC ground, and it is fed by a rectangular waveguide. All slabs are used to form the superstrate that exhibits the increasing reflection phase at th...
متن کاملA Wideband High-gain Stacked Cylindrical Dielectric Resonator Antenna
Abstract—A new wideband and high-gain dielectric resonator antenna (DRA) is proposed. Three cylindrical dielectric resonators (DRs) with different materials and different sizes and a metallic cylinder are designed to obtain a wideband bandwidth and a high gain. The stacked structure provides a wideband bandwidth, and the cavity formed by the metallic cylinder provides a high gain. The measured ...
