Leaky-Wave Antenna on Substrate-Integrated Waveguide with Radiation Pattern Controlled by DC Voltage

Popis výsledku v původním jazyce

This paper presents the application of a substrate integrated waveguide (SIW) for the design of a leaky wave antenna (LWA). The antenna radiates through a wide slot in the top wall of the SIW structure in the forward direction. The effective width of the slot is varied by changing capacitances of two arrays of varactors connected between slot edges and inserted conducting strips. The radiation pattern of the antenna is by this way controlled by DC bias, which sets the capacitances of varactors. The maximum radiation direction in elevation can be varied within 35degree by changing the DC bias from 2 to 12 V. This elevation angle is measured from the broad side direction perpendicular to the antenna substrate. The measured antenna characteristics are in accord with those predicted by simulation. The antenna can be simply fabricated by a PCB technology.
