A Novel Ring Antenna with Pattern and Frequency Reconfigurability

摘要：

A novel ring antenna with pattern and frequency reconfigurability b proposed in this paper. Ring structure can increase the effective length of radiation element of an antenna within the finite dimension. The proposed antennas dimension with respect to the operating frequency(2G Hz and 2.4GHz) is 44mm×44mm. Three switches are used in the antenna to achieve different radiation patterns and operating frequencies. When only one of the three switches is closed, the antenna can provide the patterns that point at two of the six directions at 2CHz. When two of the three switches are closed, the antenna can provide two of the six different patterns at 2.4GHz. The bandwidths are 1.85GHz2.10GHz for 2GHz, and 2.2GHz-2.5GHz for 2.4GHz. The antenna can be used in many applications.
