Abstract
The invention discloses a plane microwave passive device capable of reconfiguring four microwave functions, belonging to the technical field of reconfigurable circuits. It includes a plane structure composed of a microstrip structure layer, a dielectric layer and a metal ground plate connected in sequence, and the microstrip structure layer is arranged on the dielectric layer. The microstrip structure layer includes a rectangular microstrip sheet, ten microstrip lines, a hairpin microstrip structure, twelve PIN diodes and four ports. Through the control of the forward and reverse voltages of the PIN diode, the on-off of the circuit is controlled, and the function of the device can be reconfigured. Planar microwave passive devices include four functions: filter, antenna, power divider and coupler. The filter belongs to the hairpin type band-pass filter, the antenna belongs to the microstrip rectangular patch antenna, the power divider belongs to the microstrip half power divider, and the coupler belongs to the microstrip coupling line directional coupler. The planar microwave passive device of the invention has a simple and compact structure and wide application range, realizes rapid switching among the four functions, and realizes time-sharing independent work without affecting each other.
