Focusing the radiation pattern to the front or back side can effectively increase the directivity of the antenna, and the transceiver signal from the front or back can also take advantage of the diode switching on or off effectively, which is easy to implement. This design can effectively reduce the large number of antennas used for RFID application in the detection conveyor belts. Thus it can not only reduce the space occupied, but also reduce the cost. The proposed pattern reconfigurable antenna is a slotted substrate integrated cavity antenna, in which lots of vias are used to form the dominant TE101 mode. To reduce the number of vias, L-shaped slotted substrate integrated cavity antenna operating its dominant TE (0.5, 0, 0.5) mode is also proposed. Moreover, the use of the L-shaped slot as a boundary condition not only can effectively reduce the number of vias but also can maintain the antenna gain and radiation efficiency. The operating mechanism and the detailed pattern reconfigurable antenna design are discussed in this thesis. Experimental and simulation results are presented to confirm the feasibility of the antenna design. 許博文 2012 學位論文 ; thesis 89 en_US |

碩士 === 國立臺灣大學 === 電信工程學研究所 === 100 === A novel design for pattern reconfigurable antenna, which uses pin diodes to control the pattern in the front or back side direction, is proposed. Focusing the radiation pattern to the front or back side can effectively increase the directivity of the antenna, and the transceiver signal from the front or back can also take advantage of the diode switching on or off effectively, which is easy to implement. This design can effectively reduce the large number of antennas used for RFID application in the detection conveyor belts. Thus it can not only reduce the space occupied, but also reduce the cost.
The proposed pattern reconfigurable antenna is a slotted substrate integrated cavity antenna, in which lots of vias are used to form the dominant TE101 mode. To reduce the number of vias, L-shaped slotted substrate integrated cavity antenna operating its dominant TE (0.5, 0, 0.5) mode is also proposed. Moreover, the use of the L-shaped slot as a boundary condition not only can effectively reduce the number of vias but also can maintain the antenna gain and radiation efficiency.
The operating mechanism and the detailed pattern reconfigurable antenna design are discussed in this thesis. Experimental and simulation results are presented to confirm the feasibility of the antenna design.
