In this work, a compact planar dual-square ring (DSR) microstrip patch antenna is investigated to acquire dual-band resonance with dual-mode excitation for Wi-Fi/WLAN and 5G-NR based wireless applications. This dual-square ring geometry is employed on single layer dielectric, excited through EM coupling by using a quadrilateral feed patch, which offers massive flexibility in impedance matching for dual-band resonance with minimum coupling effects in common excitation and ground plane. This planar DSR structure shows the resonance at 2.4 GHz and 3.7 GHz frequency bands with bandwidths greater than 100 MHz and 200 MHz, respectively and a maximum gain response of 4.3 dBi with VSWR of 2. Here the simulation results are verified through experimental results of the fabricated antenna. This proposed antenna design can be configured for Wi-Fi/WLAN application at 2.4 GHz in lower-order resonance mode (TM 01) and for 5G-NR application by utilizing the fringing benefits of higher-order mode (TM 10) at 3.7 GHz.
In this paper we proposed a new statistical multivariate method for tracking an object in a video. This method is based on the Hottelling T 2 test which is designed to provide a global significance test for the difference between two region or two group with simultaneously measured multiple dependent or independent variables. An object to be tracked can be found by comparing its multivariate mean in the successive frame of the video. The T 2 value give the measurement of the difference of two mean vector. In this approach the object window containing the matrix of intensity value is transformed into a set of feature vector. These set of features is compared using multivariate T 2 test in the successive frame for the significant matching of the object in its nearest locality. It is observed that higher the T 2 value more is the chance of mismatching and lower the T 2 value more is the chance of matching the multi attribute. Simulation result shows that the proposed method is capable of accurately detecting the non rigid, moving object in stationary as well as non stationary camera with noisy and occlusion environment.
Boron-rich glycodendrimers containing three to six peripheral hydrophilic glucose moieties and three ortho-carborane clusters have been synthesized. Adding more numbers of glucose moieties compensated the hydrophobicity of ortho-carboranes and made...
