Proposed coplanar waveguide (CPW) fed meta-material antenna is also one of them to invoke the multiband applications in the frequency range of 5.4–5.8GHz. Meta-materials are capable to manipulate EM waves by blocking, absorbing, enhancing, and bending waves and also radiate more energy. The proposed antenna having the hairpin structure is designed with FR4 substrate having permittivity of 4.4 and...
This article presents the design of V-band hybrid coupler using new technology i.e. Substrate Integrated Waveguide (SIW) technology. This technology gives suitable components for Millimetre (mm) wave applications. In this hybrid coupler design, the level of reflection and isolation below −20dB occupy more than 2GHz of the bandwidth. The maximum peak occurs at 60GHz with a reflection coefficient of...
Feature Scenario of Substrate integrated waveguide (SIW) is a good solution for implementing centimeter and millimeter wave applications. In this paper, presented SIW π slot antenna for 57–64 GHz band applications which is designed by using Rogers RT/Duriod 5880 whose dielectric constant is 2.2 and thickness of 0.381mm. Computer simulation technology studio suite is used for simulation and Observed...
As seeing the more demand of multiband antennas for wireless communication, this Staircase-Hexagonal shaped antenna has designed. The merit of antenna eight resonance frequencies are 3.13 GHz, 8.89 GHz, 10.69 GHz, 16.79 GHz, 20.37 GHz, 26.06 GHz, 30.13 GHz, 36.26 GHz with widely used gain 5.17 dBi, 9.12 dBi, 15.83 dBi, 6.05 dBi, 5 dBi, 5.84 dBi, 5.34 dBi, 3.79 dBi respectively. These resonance frequencies...
In this paper, a reconfigurable patch antenna is designed and analyzed as a communication antenna for applications in Cognitive Radio (CR). Partial ground planes are used in micro strip patch antennas to increase bandwidth. Ring resonators are used for stopping the unwanted set of frequencies. A rectangular radiating patch on a substrate is considered with a ring resonator embedded into the ground...
This paper presents the design and implementation of a Micro strip antenna which is suitable for S-Band applications. Different antennas are existed, but microstrip based patch antennas are used mostly in IC and PCB technologies which are required for the modern applications. Micro strip antenna consists of small conducting patch made of copper or gold which are placed on a dielectric material. The...
