Popis: | An electronically beamscannable sinusoidally modulated reactance surface (SMRS) antenna and its design procedure are investigated. The antenna is composed of capacitively modulated reactance surface whose profile is a sinusoidally varying form. This configuration generates a radiating leaky wave and the antenna's radiation pattern including beam angle and beamwidth can be controlled with different parameters of the modulated surface reactance of the SMRS period. A beamscanning characteristic of the capacitively modulated SMRS antenna is shown with the design procedure and the simulated results. Designed antenna was simulated using commercial EM tool and the result was well matched with the calculated main beam direction verifying the validity of design method. About 33° of beamcanning range was obtained with the center radiating angle of 45° at 9 GHz. Designed antenna showed reasonable input matching and efficiencies within beamscanning range of the antenna. |
