Finding pair wise document relatedness plays an important role in a variety of Natural Language Processing problems. Google Trigram Method (GTM) is one of the corpus-based unsupervised method that can be used to capture word relatedness and document relatedness. It has been shown that it is possible to apply GTM to construct high quality document relatedness applications. However, there are challenges...
A $4 \times 4$ dual polarized (DP) aperture-coupled microstrip patch antenna (ACMPA) array for a universal millimeter (mm)-wave chipless RFID tag reader is presented. The mm-wave DP ACMPA array is capable of reading all types of frequency domain-based chipless RFID tags (linearly polarized, orientation insensitive, cross-polarized (CP), and DP) within its operating frequency bandwidth. The developed...
A 4×4 aperture coupled UWB microstrip patch antenna array for mm-wave chipless RFID tag reader is presented. The antenna is operating over the 21–27 GHz frequency band with 20 dBi gain. A systematic approach has been followed to design the antenna array, where, firstly a single antenna element is optimized, then a feed network using multistage power divider is designed and finally, the 4x4 antenna...
