摘要:
应用宽带叠层贴片天线的设计原理,设计宽频带叠层矩形介质谐振器天线.在矩形介质谐振器和金属地板之间插入空气缝隙或低介电常数的薄介质片,可有效降低介质谐振器的Q值,展宽介质谐振器天线的带宽.所设计的矩形介质谐振器天线带宽达59.4%,天线带内增益在4.5~6.0 dBi之间.仿真和实验结果对比验证了该设计原理的正确性及有效性.
Abstract:
The principle of broadband and stacked antenna is applied to the design of broadband, stacked, rectangular dielectric resonator antennas(DRAs). By inserting an air gap or a thin dielectric segment of lower dielectric constant between the rectangular dielectric resonator and the PEC ground, the quality factor of the dielectric resonator can be reduced effectively and the bandwidth of the antenna can be broadened. The rectangular DRA designed has a bandwidth of 59.4% and the gain of 4.5~6.0 dBi within the operating bandwidth. Experiments and simulations confirm the correctness and validation of the design principle.
