A Compact Planar Microstrip-Fed Feed Patch Antenna Using High Permittivity Substrate

摘要：

　　A compact-size Microstrip-Fed Feed Patch antenna is investigated by employing high-permittivity and low-loss substrate(i.e.,high Q×f value)for 1.9-GHz application.The antenna was fabricated on ZnO-doped Nd(Co1/2Ti1/2)O3(εr = 27.4,Q×f value of 147,000 GHz)substrate.The high permittivity and low-loss ceramic substrate(ZnO-doped Nd(Co1/2Ti1/2)O3)was used to reduce the microstrip antenna dimension on patch size.The proposed antenna occupies a size of 2.25 cm2 and obtains the operation bandwidth of about 10 MHz.Good antenna gain and CP radiation patterns have also been observed.The measured results of the performance of the antenna are presented.
