Abstract :
A differential dual-band antenna-in-package (AiP) with multilayer structure is proposed. Compared to the normal antenna, the introduced package structure changes the impedance of the antenna, such that the new resonant frequency is excited. Then, a dual-band antenna is realized. Also, in order to improve the radiation pattern in higher band, two symmetrical T-shaped slots are etched on the patch. The T-slots can help to widen the bandwidths. The realized AiP can work at 2.49 and 5.8 GHz. The 10-dB relative bandwidth is 1.61% (2.47 ~ 2.51 GHz) and 5.51% (5.67 ~ 5.99 GHz), respectively.
