Wireless sensor networks benefit greatly from advances in circuit integration and miniaturization. However, antennas are bound to specific geometries both in terms of fundamental limits and their response to immediate surroundings. As such, various successful techniques for antenna miniaturization must still be carefully tested and characterized as part of the design process of a sensor system. The work presented here fully characterizes a number of miniaturized 2.4~GHz antennas and successfully integrates designs into a sensor system using the highly integrated Single Chip Micro Mote (SCµM), which uses a crystal-less radio design resulting in the requirement of only a battery and antenna for full deployment. It was found that planar PCB trace antenna designs are an effective low cost and easily manufactured solution for such a design. It was also found that effective performance can be achieved using simple wire antenna designs. These results practically demonstrate the potential for realizing large-scale, high-density sensor networks at previously unattainable cost and effectiveness.
