Summary:
A printed multi-antenna isolation improvement with the use of decoupling network for USB dongle application is proposed. Two coupled-fed PIFAs are placed on the opposite corners of PCB and separated by a protruded ground portion, which has the width of 14 mm as a layout area. It has been experimented and verified that a decoupling network located on the space in-between the top edge of PCB and the protruded ground plane can effectively improve the antenna port-to-port isolation over 2.4 GHz and 5 GHz bands. The proposed design is a promising candidate to integrate with the module card in the form factor of a USB dongle. Detailed antenna prototype and design consideration are discussed in the article.
