Multi-band printed dipole antenna using CRC structure

This paper presents a new approach to realizing multi-band antennas using a single printed dipole incorporating compact resonant cell (CRC) structures. A triple-band antenna that operates at 900 MHz, 2.4 GHz and 5.2 GHz was constructed to illustrate the design methodology. The overall length of the triple-band antenna is 107 mm, which is shorter than the conventional single frequency design of 130 mm at 900 MHz.
