Abstract

In this paper two ultra wide band frequency reconfigurable microstrip patch antennas for cognitive radio applications were designed. The proposed antenna designs consist of a rectangular patch with microstrip feed-line, and a partial ground plane. Slots were introduced in patch and ground plane to enhance the bandwidth. The radiating element of dimension 10.5mm×14mm (L×W) was placed on FR-4 epoxy dielectric substrate with relative permittivity of 4.4. The antennas have the same patch structure but different ground plane structures. Each of the antennas can operate in UWB (3.1GHz- 10.6 GHz) range and their corresponding sub bands. Switching from UWB to sub bands is enabled by PIN diodes placed in the horizontal slot(s) in the ground plane. HFSS has been used for designing the antennas and the simulated results show that the proposed antennas have a return loss greater than 10dB over the required bandwidth of operation.

用于认知无线电应用的超宽带频率可重构贴片天线

设计了两种用于认知无线电应用的超宽带频率可重构微带贴片天线。所提出的天线设计由带微带馈线的矩形贴片和部分地平面组成。在贴片和接地面上引入了插槽以提高带宽。将尺寸为10.5mm×14mm (L×W)的辐射元件置于相对介电常数为4.4的FR-4环氧介电基片上。天线的贴片结构相同，接地面结构不同。每个天线都可以在超宽带(3.1GHz- 10.6 GHz)范围内及其对应的子频段工作。从UWB切换到子频带是通过放置在水平槽中的PIN二极管实现的。仿真结果表明，在要求的工作带宽范围内，所设计天线的回波损耗大于10dB。
