New optimized 2x2 slotted array antenna is designed using HFSS to operate at 28.1 GHz, using RT6010 substrate with height of 1.6 mm, tangent loss of 0.0023 and dielectric constant of 10.2 and overall dimension of 12x12 mm2, for 5G mobile applications. The 2x2 slotted linear array antenna achieved a high gain of 18.3 dB at 28.1 GHz with 10 dB bandwidth of 1.39 GHz, and with 83.21% of size reduction.
This research presents a wireless DC-to-DC power transfer over a short distance. Distance of remotely located target from the source coil and received voltage at the load are the major concern in the Wireless Power Transfer (WPT) applications. The inversely proportional behavior of these parameters degrades the system performance. In order to optimize these values and achieving transfer efficiency,...
This paper presents the new coil design strategy for Wireless Power Transfer (WPT) applications. In order to produce better power transfer efficiency for remotely located load, hybrid approach is proposed using two different coils such as conical and spiral. Hybrid approach refers the coil model by engaging conical as a transmitter and spiral as a receiver in a single system. The field pattern of...
In today's wireless communication, the conventional problems due to multi path environment are overcome by perfect staunch combination of Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM). In this paper, 2 × 2 Multiple Input Multiple Output antenna coupled with Orthogonal Frequency Division Multiplexing as data encoding technique schematic for both transmitter...
In this paper, a text extraction algorithm has been developed and simulated to extract text from a complex video scene by using Matlab software. Morphological operations and Haar wavelet transform have been used to design the filter to remove the non-text pixels. An experimental setup has been set and performed. The results from different tests of the algorithm have been obtained and analysed. The...
The Unmanned Aerial Vehicle (UAV) technology has seen substantial growth in the last two decades. Helical antennas play vital role in establishing reliable communication in UAV applications. In this paper, an axial mode helical antenna for unmanned aerial vehicle (UAV) applications is proposed. The antenna is simulated and the performance analysis is presented. The antenna with 3 turns and a pitch...
A Tri-band G-shaped Microstrip Monopole antenna suitable for the ISM band wireless applications in MIMO environment is presented in this paper. The novelty contributed in this work is the appropriate selection of dielectric substrate, the logical modifications in the existing antenna length and width, and the connection of the ground planes on both sides of the existing G-shaped antenna. The proposed...
