摘　　要：要本文提出了1种有效减小移动终端贴片天线尺寸的方法,通过在地板上选择恰当的位置,使贴片作为激励源激励起来地板,从而在尺寸相同的情况下,能够实现更宽的带宽。基于此想法,通过添加短路柱以及刻槽,利用偏馈的方法激励半模贴片天线的前2个模式,设计出1个工作在5.15~5.85GHz的半模贴片天线,天线的尺寸为0.39λ_(0)×0.33λ_(0),剖面为0.022λ_(0),效率均高于-2.25dB。相较于放置于地板中心位置的贴片天线,具有更小的尺寸和更低的剖面。In this paper,an effective method to reduce the size of mobile terminal patch antenna is proposed.By selecting the appropriate position on the floor,the patch can be used as the excitation source to excite the floor,so as to achieve a wider bandwidth under the condition of the same size.Based on this idea,a half-mode patch antenna working at 5.15~5.85 GHz is designed by adding a short circuit column and grooving,using the partial feed method to stimulate the first two modes of the half-mode patch antenna.The antenna size is 0.39λ_(0)×0.33λ_(0),the profile is 0.022λ_(0),and the efficiency is higher than-2.25 dB.Smaller size and lower profile than a patch antenna placed in the center of the floor.
