摘要： Disclosed is a Radio Frequency Identification (RFID) tag antenna. The tag antenna includes a lower dielectric substrate and an upper dielectric substrate. The lower dielectric substrate is provided at a lower surface thereof with a ground plane and at an upper surface thereof with two microstrip lines. The microstrip lines each have an open-end, the open ends spaced apart from each other from a middle of the lower dielectric substrate while facing each other to form a radiating slot from which radiation of electromagnetic waves occurs. The upper dielectric substrate is provided at an upper surface thereof with at least one electric capacitive device and is stacked on the lower dielectric substrate. The RFID tag antenna enhances radiation efficiency while achieving miniaturization.

摘要： A large data transmission method in a sensor network based on a media access control (MAC) is provided. The method includes dividing data to be transferred into a plurality of data segments; generating a plurality of media access control (MAC) segmented data frames by including in each data segment an indication that the data is generated by segmentation and assigning a sequence number to the data segment; transmitting the generated MAC segmented data frames sequentially; receiving a MAC reception failure frame indicating reception failure for a predetermined period of time from a receiving sensor node after completing the transmitting of all the MAC segmented data frames; and retransmitting the MAC segmented data frames which correspond to at least one sequence number included in the received MAC reception failure frame. Accordingly, large data transmission times can be reduced in a MAC for a sensor network.
