Abstract

A low-cost, printed single-plate two-antenna system suitable for multiple-input multiple-output (MIMO) applications operating at the 2.4 GHz WLAN bands is presented. It is best embedded inside the wireless access point (AP) from the size consideration. The antenna consists of two folded monopoles orthogonally located at the edges of a rhombic ground plane. The feed points drive the monopoles from the edges. The two monopoles are joined together near the intercept of the edges. This configuration provides diverged patterns with a good isolation characteristic through the 90° polarization. Impedance matching for the 2.4 GHz bands can easily be achieved by tuning the feeding positions. Measured envelope correlation is less than 0.06 within the band of interest.
