Abstract :
Compact RF transceivers with integrated sensors (called "motes") are used in wireless sensor networks to monitor such things as patient vital signs, environmental parameters and manufacturing processes. One of the limiting factors for mote size and efficiency is the antenna. This paper examines, in both the transmitting and receiving modes, the impedance matching for the antenna used on a commercially available mote and shows that significant improvements in efficiency can be made through improved antenna impedance matching
