Communication between on-chip cores is a challenging issue for high-performance network-on-chip (NoC)design. Wireless NoC (WiNoC) represents an alternative design for planar wired interconnects, aiming to reduce latency and improve bandwidth. In this paper, a novel on-chip fractal antenna is designed and characterized. In order to disseminate interference affecting NoC performance in order to enhance on-chip quality of service (QoS), a set of exclusive sub-channels are assigned to each antenna. The proposed antenna has two wide bands (bi-WB)—B1 and B2, of (63–78) GHz and (101–157) GHz, respectively. The multi-band antenna allows different channel allocations for on-chip core communications. This WiNoC design exhibits improved performance, due to its enhanced antenna bandwidth and the benefit provided by the developed algorithm that can scan and compare to assign the best (upload or download) sub-channels to each antenna.

This paper opens investigations on patch antenna and simple and deformed trapezoidal shape invariants. The simplest and the most compact the antenna is, the most efficient it is and the less it costs. When we aim for a wideband communication, we should design our antennas while taking into account many essential electromagnetic characteristics. This paper studies different patch antenna shapes based on trapezoids. Curves are explored to modify these shapes and to ameliorate the quality of wideband antennas. The moment method is used here as a technique of analyzing (MOM) electric and magnetic fields. Actually, novel invariants in the explored shapes, were underlined in this paper and orient the antenna designer to take care of their dimensions as well as these variables affects closely the bandwidth offered consequently by the designed antenna.
