- Abstract
- In this paper, a reconfigurable single port triangular patch antenna with polarization diversity is proposed. The proposed antenna consists of a coaxially-fed corner-Truncated equilateral triangular patch, two small parasitic triangular patches in the vicinity of truncated corners, two PIN diodes located between truncated corners of the patch and parasitic small patches as switch, two RF choke inductors, and dc bias line for practical design. The antenna has four different radiation modes depending on the diodes states (on and off): high-frequency linear polarization, low-frequency linear polarization, left-hand circular polarization, and right-hand circular polarization. The switchable antenna is designed to operate in 2.4 GHz ISM band for wireless communication applications such as wireless local area network and global positioning system.
