Design and Analysis of Fractal Loop Antenna Array for Rectenna Applications, respect to single element, and the 1 × 2 array implementations (with different feed orientations) were experimented with same magnitude and phase (broadside case). The proposed array design is triple band in nature (1.42/1.92/2.42 GHz) and can accept the EM signals at the peak gain 2.77/4.12/6.16 dB, respectively.

Design of High Isolation MIMO Antennas for Ultra-Wide Band Communication, isolation is achieved up to 29 dB in a frequency range of 3.1–10.6 GHz with proper impedance matching. The proposed UWB antenna has been desirable in terms of antenna size, geometric complexity, bandwidth, gain, and isolation level.

https://doi.org/10.1007/978-981-99-0628-4gnition system which will efficiently detect the abnormal activities happening at the ATM room. We conducted the experiment to assess the proposed system performance with existing methods our system achieves better accuracy with less error rate when varying the bin size.

Horst Senger,Klaus Humbeck,Hilmar Schillered, the identified letters are grouped to reproduce the first symbol strings. The proposed method for developing high-performance OCR software for Roman-text includes the extraction of image, preprocessing highlights, and the creation of classification algorithms.
