提出了一种新型的紧凑型圆极化微带宽带印刷贴片天线。该天线由一个连接在局部矩形地平面上的钩形分支和一个L形微带馈电的反向不等臂组成，使天线具有宽带圆极化特性。测量结果显示，所提出的紧凑型（44 × 44 × 1.6 mm（3））天线在10 dB阻抗带宽处获得3.12 GHz（56%，2.25-4.0 GHz），在3 dB处的轴比（AR）带宽为3.48 GHz（63.61%，2.38-4.60 GHz）。不同的设计参数和测量和仿真结果的各种特性的设计天线的参数研究，以验证性能的辐射机制。最后，通过缩放，所提出的天线的尺寸不改变其他参数，实现了宽阻抗和AR带宽。由于简单的平面结构和具有宽带CP特性的缩放尺寸，所提出的天线确实适用于各种无线通信系统，例如ISM、WiMAX、WLAN、卫星通信、无绳电话、天气雷达系统和较低频段CP类型应用。
In this paper, a novel compact circularly polarized (CP) monopole wideband printed patch antenna is proposed. The antenna consists of a hook-shaped branch connected at the partial rectangular ground plane and reversed unequal arm with an L-shaped microstrip-feed which helps the antenna achieve wideband circular polarization property. The measured results display that the proposed compact (44 x 44 x 1.6 mm(3)) antenna acquires 3.12 GHz (56%, 2.25-4.0 GHz) at the 10-dB impedance bandwidth, and the axial ratio (AR) bandwidth at 3-dB is 3.48 GHz (63.61%, 2.38-4.60 GHz). A parametric study of different design parameters and measured and simulated results of the various characteristics of the designed antenna is presented to verify the performance of the radiation mechanism. Finally, by scaling only, the dimensions of the proposed antenna without changing another parameter, a wide impedance and AR bandwidth are achieved. On account of the simple planar structure and scaling dimension with broadband CP property, the proposed antenna does apply in a variety of wireless communication systems such as ISM, WiMAX, WLAN, satellite communications, cordless telephones, weather radar systems, and lower frequency bands CP type applications.
