초록

A frequency reconfigurable planar inverted-F antenna (PIFA) using a PIN-diode is presented for mobile-WiMAX applications. The antenna in this study not only alters the frequency bands of mobile-WiMAX but also has a small profile using electro-magnetic coupling in a high dielectric constant substrate. The PIFA consists of a main radiator, an additional parasitic radiator, a coupled radiator, two PIN-diodes, and control circuits. One diode is placed between the main and additional parasitic radiator on the top side, and the other diode is placed between a coupled radiator and ground. Depending upon whether diodes are on or off, the antenna operates over 2.3 to 2.4 GHz, 2.5 to 2.7 GHz, and 3.4 to 3.6 GHz for worldwide mobile-WiMAX bands. All simulated and measured results for the proposed antenna are presented and they show good agreement.
