This paper presents a novel topology of isotropically radiating “smart cubes” for use in wireless sensors. The novelty of this antenna is the use of 3D frequency selective surfaces which are used both for creating the desired radiation pattern and for creating a core which is electrically isolated from the antenna at the frequency of operation. The core allows for an embedded power source, processor, amplifier, and/or secondary antenna without interfering with the operation of the radiator. As demand for wireless sensors continues to grow, this device will allow for the implementation of sensors in a wider range of applications including autonomous “smart skins”, biosensing, and RFID-enabled sensors. The prototype is printed on glossy paper using a conductive ink, which gives it the potential for low cost production, allowing it to be used in a variety of applications requiring large numbers of sensing nodes, while meeting enhanced data processing, security or autonomy requirements.
