Abstract

An antenna designed for a spherical surface with a near-isotropic radiation pattern is presented in this work. The antenna is designed for wireless, UHF RFID sensors. It is electrically small with a diameter of 52 mm and operates in the UHF RFID frequency band. The antenna consists of a spherical ABS plastic shell surrounding a standard FR4 printed circuit board. This allows ample space for sensors and electronic circuitry. A prototype sensor platform has been manufactured and tested. The outer shell was produced using a 3D printer. An Alien Technology Higgs 3 RFID IC was used to test the basic functionality of the antenna. Simulation and measured results are presented.
