设计了一种谐振频率为5.8GHz的圆极化微带贴片天线。该天线的辐射贴片是基于双馈椭圆形贴片，通过增加四分之一波长谐振器和圆形槽修改。由此产生的贴片类似于瓢虫，因此被称为“瓢虫天线”。设计的天线增益为6.88dB，回波损耗为25dB。它在5.8 GHz处具有0.48 dB的轴比，这表明它具有良好的圆极化。瓢虫天线具有全向辐射方向图，适合于微型飞行器（MAV）的近距离MPT操作。
This paper is based on a circular polarized microstrip patch antenna which is designed for microwave power transmission with resonating frequency of 5.8 GHz. The radiating patch of the antenna is based on a dual feed elliptical patch which is modified by adding quarter wavelength resonators and circular slots. The resultant patch resembles to a ladybug and hence the name “Ladybug antenna”. The designed antenna has a gain of 6.88 dB and return loss of 25dB. It has 0.48 dB axial ratio at 5.8 GHz which shows that it has good circular polarization. The Ladybug antenna has omnidirectional radiation pattern which is suitable for short range MPT operation of Micro Aerial Vehicles (MAV).
