A novel single‐fed circularly polarized wideband, compact and lightweight microstrip patch antenna (MPA) is proposed. The antenna is designed in a simple two‐phase procedure to achieve wideband and circular polarization. In the first phase, an off‐centered L‐shaped feeding arrangement is employed to obtain wideband (|S₁₁| < −10 dB) over 10.6 GHz to 14.7 GHz with an improved peak gain of 5.25 dBi. In the second phase, the radiating patch is symmetrically truncated and two modified‐parasitic patches are added to ensure <3 dB axial ratio over 11.4 GHz to 12.8 GHz. A prototype has been fabricated and the measured results show close agreement with the simulation. The proposed antenna is suitable for fixed satellite and broadcast satellite communication in Ku‐band range.

偏心馈送的紧凑型宽带天线，带有截短的角和用于圆极化的寄生贴片

提出了一种新颖的单馈圆极化宽带，紧凑轻便的微带贴片天线（MPA）。天线采用简单的两阶段程序进行设计，以实现宽带和圆极化。在第一阶段，采用偏心的L形馈电装置来获得10.6 GHz至14.7 GHz的宽带（| S ₁₁ | <-10 dB），并具有5​​.25 dBi的改进峰值增益。在第二阶段中，辐射贴片被对称地截断，并添加了两个修改后的寄生贴片，以确保在11.4 GHz至12.8 GHz范围内轴向比小于3 dB。已制作出原型，测量结果与仿真结果非常吻合。所建议的天线适用于Ku频段范围内的固定卫星和广播卫星通信。
