Abstract
With the WiMAX (Worldwide Interoperability for Microwave Access) protocol springing up, the mobile device demand are getting more and more, and multi-band antennas emerge. Designing antenna becomes harder because mobile devices are getting smaller and thinner. This thesis focuses on multi-band manipulation by using spiral-shaped monopole for high-frequency band and planar inverted-F antenna (PIFA) for low-frequency band, and feeding them with an offset microstrip line to make the characteristics in high and low frequency bands can be adjusted almost independently.
