Microwave application technologies such as microwave heating, microwave assisted chemistry, etc. are of the innovative green technologies. This paper proposes a chip-size structure for continuous microwave irradiation. It consists of a post-wall waveguide and a micro channel arranged among the metallic posts (pillars), and utilizes the 24.125GHz ISM band instead of the commonly used 2.45GHz ISM band to realize miniaturization. The micro channel can be embedded easily by using the gaps between the metallic posts of the post-wall waveguide, simultaneously keeping the microwave energy confined. For the input of microwave power, two types of the irradiation structure are designed. One is a structure with coaxial transmission line to post-wall waveguide transformer. The other is a structure with microstrip feed line. The temperature-time profiles of some solvents under microwave irradiation are examined numerically and experimentally with microwave power sources of about 1W.
