Doherty Power Amplifier Chip Integrated Slot Antenna at 26GHz

This paper presents a Doherty power amplifier chip integrated Slot Antenna. To facilitate gold wire bonding, the thickness of the antenna substrate is only 0.127mm. The antenna adopts power division structure. By using double feed points, the slot can superimpose and excite additional resonant modes to expand the bandwidth of the antenna. After gold wire bonding with the previous DPA. The impedance bandwidth of proposed antenna is about 41.92%, and the gain in the maximum radiation direction is about 5.1dBi. The overall link has low loss and good radiation performance, which provides a feasible direction for the integration of antenna and power amplifier.
