摘要

本文设计了一种改进了带宽和回波损耗的微带贴片天线。在传统圆极化矩形微带贴片天线(CP RMPA)的基础上，在辐射贴片中引入两个缝隙，观察其对天线回波损耗和带宽等特性的影响。通过引入两个时隙，实现了带宽和回波损耗的增强。带宽从5.8%到6.26%，回波损耗从-30.219dB到-52.54dB。在CST Studio软件中，采用介电常数为4.3的FR-4环氧树脂作为衬底材料，同轴探头作为馈源，设计和建模了传统和开槽CP RMPA。并对槽面积进行了变化分析。

Slotted Circular Polarized Rectangular Microstrip Patch Antenna with Enhanced Bandwidth for Wireless Communication in 2.45GHz

In this paper, a microstrip patch antenna with improved bandwidth and return loss is design. From the conventional circular polarized rectangular microstrip patch antenna (CP RMPA), two slots were introduced in the radiating patch, and its effect on antenna characteristics like return loss and bandwidth were observed. By introducing two slots, an enhancement in bandwidth and return loss has been achieved. From 5.8% to 6.26% bandwidth and return loss from -30.219dB to -52.54dB. Both conventional and slotted CP RMPA was designed and modeled in CST Studio software, using a FR-4 epoxy as substrate material with dielectric constant $\varepsilon$r of 4.3 and uses a coaxial probe as feed. The slot area were also varied and analyzed.
