Abstract
The invention discloses an artificial antenna mismatching load which is used on a transmitter and capable of simultaneously adjusting standing wave ratio and phase. The artificial antenna mismatching load consists of two parts, i.e. an adjustable mismatching load and a phase adjusting device. The phase adjusting device also comprises a casing as well as a transmission part and a phase adjuster which are arranged in the casing. The adjustable mismatching load part has a plate-line structure for transmission, is made of special absorber material, and utilizes a knob to drive a gear and a rack to move an absorber so as to cause the absorber to move on a plate line and generate different energy absorption, therefore, different standing wave ratios can be formed and the mismatching load capable of adjusting the standing wave ratio is achieved. The phase adjusting device part adopts a coaxial-line principle and utilizes a knob to drive the gear and the rack for transmission so as to drive an inner conductor and an outer conductor to move simultaneously, therefore, a phase difference is changed and the aim of phase adjustability is achieved. The artificial antenna mismatching load combines the two parts and more efficiently improves the work efficiency of a debugging person during transmitter debugging.
