A circularly polarized (CP) substrate integrated waveguide (SIW) cavity-backed antenna based on slot split ring resonator is proposed. The circularly polarized wave is generated by a split ring-slot etched in the upper metal layer of SIW cavity resonator. A simple coaxial probe is employed to excite this slot split ring resonator and radiate left-handed circularly polarized (LHCP) wave. The proposed...
It is a common problem for Wireless LAN (WLAN) users when they face more than one available Access Point (AP): which one may serve them better? In the real world, most WLAN devices and users select the AP by Received Signal Strength (RSS), which doesn't consider the load of APs. Therefore, the RSS-based scheme may result in load imbalance and utilization degradation. This paper proposes a simple scheme...
The rapid growth in complexity of the automotive ECU (Electronic Control Unit) networks has posed challenges in real-time network management, which collects network information for fault diagnostic systems. This paper proposes a dynamic network management framework based on the OSEK Network Management protocols, which can automatically adapt to the unstable network load. A method to calculate appropriate...
