The paper emphasizes on the design and performance analysis of high directivity FR4 substrate slotted defected ground microstrip patch antenna for X-Band applications. The antenna has been fed by microstrip feedline via impedance transformer to match the impedance of proposed antenna with the 50Ω impedance of co-axial connector used for feeding power to the antenna. The propounded antenna has been...
In this paper, the design and performance analysis of dual circular stacked microstrip patch antenna for S-band applications has been proposed. In the proposed antenna design, the substrate of material FR 4 having dielectric constant 4.4 have been used. The ground, patch and feedline are of copper material. The proposed antenna has two circular stackings on the patch and the antenna has impedance...
In this paper, a novel multiple slitted and circular stacked microstrip patch antenna with high gain has been proposed. The composite effect of employing slots and stacking provides enhanced return loss (dB), high gain (dB) and directivity (dBi). The proposed antenna design employ FR4 material as a substrate having dielectric constant 4.4. The copper material has been used for patch and ground. The...
This paper concentrates on the design and performance analysis of blind hole substrate slotted microstrip patch antenna design for X-band applications. The anticipated antenna has been designed using Flame Retardant 4 (FR4) substrate of dielectric constant, εr of 4.4 sandwiched between copper patch and ground plane. The intended antenna has compact area with impedance bandwidth of 560 MHz (7.67 GHz–...
In this paper, a microstrip rectangular patch antenna with reduced ground capable of operating in terahertz (optical) frequency range has been designed and proposed. The antenna has been fed by microstrip feedline which has an input impedance of 292.6 Ω closely matching with the input impedance of SMA connecter of impedance 292 Ω for maximum power transfer to the antenna. The ground and patch of the...
In this paper, a flexible I shaped stacked novel ultra wideband (UWB) antenna with defected and reduced ground resonant at 1.26 GHz with an impedance bandwidth of 1.278 GHz (1.0596 GHz to 2.3374 GHz) has been proposed which can be suitably employed for satellite reconnaissance, amateur radio, future soil moisture and sea surface salinity mission applications. The material employed for substrate is...
This paper presents an ultra wide band (UWB) multi resonant optical antenna. In the proposed antenna design, substrates of material FR4 having dielectric constant 4.4 have been used. The aperture coupled feeding technique has been used in the proposed antenna design. The ground, patch and feed line are of copper material. The proposed antenna design is a multiband optical antenna having multiple resonant...
This paper presents the design and performance analysis of an efficient solar energy harvesting single axis sun tracking system employing dynamic offset parabolic mirrored reflector dish to increase the efficiency of solar energy harvesting system. The performance of proposed solar energy harvesting system has been analyzed by comparing the output of proposed system with static solar panel and solar...
