Abstract: A new integration technique for antenna and Power Amplifier (PA) without complex impedance matching network is presented. This method helps to reduce the losses, power consumption and overall size of the RF front-end modules without affecting the efficiency of the PA. This design technique utilizes a capacitively coupled feeding mechanism to control the input impedance of the antenna. By optimizing the antenna dimension the impedance of first two harmonics (2.4 and 4.8 GHz) of a Class-B PA can be matched without additional matching circuit and the PA can provide a maximum efficiency of 70% at the operating frequency of 2.4 GHz. Thus, the proposed integration technique reduces the overall size of the RF front-end module without affecting the output efficiency of the PA. The antenna provides an axial beam with a maximum gain of 6.18 dBi and 87% radiation efficiency.
