Abstract

A class-E power amplifier integrated with a rectangular ring planar inverted-F antenna (PIFA) is presented in this paper. The proposed PIFA is very compact and occupying less volume 16 × 10 × 5.5 mm3. The measured result shows that the proposed PIFA offers an impedance bandwidth of 250 MHz from 2.3–2.55 GHz, which is useful for LTE band 40 and WLAN (2.4–2.48 GHz). The maximum power-added efficiency (PAE) of class-E power amplifier is found to be 70% at 2.3 GHz. Further, the proposed PIFA is integrated with the class-E power amplifier to design an active-integrated antenna. The simulated results of the active-integrated antenna are presented. It is found that the gain of the active-integrated antenna system is increased from 2.4 dBi (passive) to 17.2 dBi (active).
