摘要

提出了一种对角同轴馈电的双频双槽加载微带天线。矩形贴片用作散热器，在其上创建两个窄槽。这些缝隙和馈电位置使得天线的频率和极化都是可重构的。该天线在4.0和4.9 GHz频段的带宽分别为550mhz和180mhz。这种带宽足以满足许多应用，如卫星和雷达通信。利用HFSS V.17.0对天线进行了分析和仿真。仿真天线在4.9 GHz时与中心频率的10∶1增益带宽为12.5%，在4 GHz时为4.7%。提出的工作在4.9 GHz频率下提供7.8dBi增益，在4 GHz频率下提供7.1dBi增益。该天线提供圆极化(LHCP和RHCP)。这种天线的总尺寸为60 × 60 × 3.8毫米，在贴片上创建的插槽尺寸为18 × 1毫米，与传统天线相比非常紧凑。

Analysis of dual band double slot loaded microstrip patch antenna

A dual band double slot loaded microstrip antenna with a diagonal coaxial feeding is proposed. Rectangular patch is used as radiator over which two narrow slots are created. These slot and feed position make antenna both frequency and polarization reconfigurable. The bandwidth of this slotted antenna is 550 MHz and 180 MHz at 4.0 and 4.9 GHz respectively. This bandwidth is sufficient for many applications like satellite and radar communication. The antenna is analyzed and simulated using HFSS V.17.0. The 10∶1 gain bandwidth of the simulated antenna with respect to center frequency is 12.5% at 4.9 GHz and 4.7% at 4 GHz. The proposed work provides 7.8dBi gain at frequency 4.9 GHz and 7.1dBi at 4 GHz. The proposed antenna provides circular polarization (both LHCP and RHCP). This antenna having an overall dimension of 60 × 60 × 3.8 mm3 and the dimension of slots created over patch is 18 × 1 mm which is very compact compared to the conventional antenna.
