| 摘要: |
| 设计了一种用于移动载体平台的新型天线，天线为圆极化、宽带、宽角覆盖且可嵌入
载体平台安装。在微带天线的基础上，通过将高介电常数、空气介质层、频率选择表面(FSS
)技术结合
使用，实现了可嵌入式电小宽频带圆极化微带天线：对应波长仅为038λ（长）×0
38λ（宽）×009λ（高）；相对带宽为14%；圆极化增益能在120°范围内大于
-1 dB。目前，该天线已应用于实际工程中，并取得了良好效果。 |

| Abstract: |
| This paper presents a novel antenna for mobile platform application.The circula
rly polarized ant
enna is featured by broad bandwidth and wide-angle coverage,and can be embedded
in carrier platform installation. Based on microstrip antenna, through combinati
on of the high dielectric constant, air dielectric layer and FSS (Frequency Sele
ctive Surface) technology, the electrically small broadband circularly polarized
microstrip antenna is realized.The corresponding wavelength is 0.38λ(leng
th)×0.38λ(width)×0.09λ(height), relative bandwidth is 14%,and circul
ar polarization gain is larger than -1 dB within 120 degrees.
The antenna has been used in practical projects and it performs well. |
