Investigations of Reduction of Mutual Cou- Pling between Two Planar Monopoles Using Two Λ/4 Slots

Abstract

This article presents a simple structure for reducing mutual coupling between two diversity planar monopole antennas for WLAN 5.2/5.8GHz applications. The structure has two λ/4 (λwavelength in the substrate) slots cut into the ground plane between the two monopoles. In 0.5λo (λo-wavelength in the air) of the antenna spacing, mutual coupling was −33.3, −21.1… (More)
