Abstract: Embodiments of the present disclosure relate to improvement on isolation between antennas and provide an antenna, an antenna array comprising the antenna and a communication device comprising the antenna array. The antenna comprises an improved feeding network. The feeding network comprises: first and second ports each configured to transmit and/or receive a signal; first and second feed lines coupled in parallel between the first and second ports and formed into a continuous conductive loop; and first and second feeders each arranged to couple to a first node on the first feed line and to a radiating element of the antenna, and third and fourth feeders each arranged to couple to a second node on the second feed line and to the radiating element.

Abstract: A network device and method for network selection and network switching are provided. The network device is communicating with user equipment (UE). The network device includes a processor and a memory for storing instructions executable by the processor. The processor is configured to request the UE to report speed information, receive a measurement report from the UE, the measurement report including speed information of the UE, and determine whether to switch network for the UE based on the speed information.
