The radio frequency communication device is usually composed of active (power amplifier and low-noise amplifier) and passive (antenna and filter) elements. To reduce the size of radio frequency circuit, active integrated antenna design have been proposed, which allows the antenna to integrate with the power amplifier, forming a single compact structure. A micro-strip fed triangular ring slot antenna with a fundamental mode at 5.5GHz. To suppress the additional harmonics mode exited by the triangular ring slot, a single inverted U-shaped slot (defected ground structure) is integrated into the triangular ring slot.
