In this paper, two planar inverted-F antennas on a slitted ground plane is proposed for MIMO mobile terminal. This antenna is designed to operate at 5 GHz with 1 GHz bandwidth. In simulation stage, the length and width of slitted are varied. The optimum slit's dimension is shown to be λ/4 length and 0.0333λ width, which produced reflection coefficient of −16.38 dB and isolation of −23.52 dB at 5 GHz,...
In this paper, a new FSPA for new application — outdoor RF energy harvesting will proposed and designed. A new FSPA structure will joint with folded patch meander line and two pairs of slot embedded into its ground plane. A less profile, less cost and ease to fabricate the folded shorted patch antenna (FSPA) will introduced. The proposed antenna designing and performing using Computer Simulation Technology...
IoT technology has improved the quality of life as well as provides intelligence and comforts to the user. A Wireless Sensor Networks (WSN) technology is one of the powerful technologies that enable IoT objects to communicate with each other. Device-Free Localization (DFL) system exploits changes in radio signals across different environments aims to detect and track entities without requiring them...
This paper describes the design procedure of a deployable antenna for Cubesat applications operating in the UHF frequency band of 437 MHz. Due to the expected large size for operation in this band, the meanderline and Vivaldi miniaturization and broadbanding techniques are used to obtain a wider impedance bandwidth. This is to ensure the size compatibility of the proposed antenna to the compact Cubesat...
A new type of Frequency Selective Surface (FSS) with miniaturized resonator element is proposed. The FSS structure is shown to have a FSS unit cell dimension that is miniaturized to 0.067 . Miniaturization of the FSS unit cell is achieved by coupling two meandered wire resonators separated by single thin substrate layer. The capacitance due to the small separation between the meandered...
A novel 3D Frequency Selective Surface (FSS) with horn shaped resonators is proposed which exhibits a very wide stop band. This new horn shaped resonator is a modification from a 3D FSS consisting of square cylinder unit elements. This feature introduces frequency-selective surfaces with the added advantage of lowering the sensitivity of the FSS frequency response with respect to the incidence angle...
