Antenna integration is a relative new concept for the miniaturization of Radio Frequency (RF) transceivers where a key problem is to achieve a small size at low cost. Traditional solutions, using ceramic materials, are too costly. Additionally, the current trend in RFID applications is the development of smaller and cheaper tags. In this paper, we present an elegant and low-cost Antenna-in-Package (AiP) solution for RFID tag applications. A printed dipole antenna that integrates the balun function with improved filtering characteristics is designed on a low-cost dielectric material. Simulation and measurement results verify the performance of the proposed antenna.
