Design Of Dual-Band Compact Ceramic Chip Antenna For Terminal Applications

In this paper, a novel dual band compact antenna based on planar inverted-F antenna (PIFA), ceramic substrate and interdigital coupled structure are proposed. It has compact size with the dimensions of 10.2*3*2.5mm(3). The operating mechanisms are illustrated and the study on the key dimension parameters is given. Both the simulation and measurement results are shown to verify the good performance of the antennas. The antenna can operate at both 1.575GHz and 2.45GHz and offers a maximum total gain about 3.21dBi and 3.5dBi respectively. It is suitable for multifunctional applications in terminals.
