As a new trend, torus-based optical networks-on-chip (ONoCs), which can be considered as an extension of a 2-D network topology based on a mesh topology, can overcome the bandwidth limitation of a conventional electrical networks-on-chip. Although ONoCs have many advantages, crosstalk and insertion loss are the two main causes of the performance degradation and network scalability constraints. When...
A new type of dual-polarization and dual-frequency multilayer-stacked microstrip array antenna is introduced. The feeding mechanism of the element is the aperture coupling for one polarization and the direct feeding for the orthogonal polarization. The microstrip element exhibits a wideband of operation. A slot etched on driven patch is used to improve isolation performance of the proposed antenna...
A novel millimeter wave monopulse slotted waveguide array antenna with a central hole for infrared sensor use is presented. The amplitude distribution is optimized, and a monopulse comparator is designed to feed the proposed array. This millimeter wave array antenna has been fabricated and measured. The gain of the sum beam is higher than 32dB, whereas the zero depth of the difference beam is lower...
