摘要

提出了一种激发圆柱介质谐振器(DR)天线电单极子模式(TM01δ模式)的非侵入馈电方法。该馈电包括具有四个对称桩的非谐振圆形金属贴片，由同轴探头馈电。DRA的单极模式是由贴片而不是探针激发的，因此无需在DR上钻一个轴向孔以进行传统的探针插入(侵入式进给)。通过ANSYS HFSS仿真，验证了新馈源的可行性，并与相同模式下的探针馈源DRA进行了比较。

A Non-Invasive Feed Approach to Excite the Electric Monopole Mode of a Dielectric Resonator Antenna

A non-invasive feeding method to excite the electric monopole mode (TM01δ mode) of a cylindrical dielectric resonator (DR) antenna or DRA is presented. The feed comprises a non-resonant circular metallic patch with four symmetric stubs, fed by a coaxial probe. The monopole mode of the DRA is excited by the patch rather than the probe, hence the need to drill an axial hole in the DR for conventional probe insertion (invasive feed) is avoided. Using ANSYS HFSS simulations, the viability of this new feed is demonstrated and results are compared with that of a probe-fed DRA exciting the same mode.
