Omnidirectional wrapped microstrip antennas for MIMO linear arrangements in laptops

Multiple omnidirectional wrapped microstrip antenna (OWMA) elements integrated along the top edge of a laptop screen are studied in this paper. Linear arrangements of two and four antenna elements are considered. The performance is evaluated both in terms of the individual antenna characteristics and mutual coupling and correlation as a function of the element spacing. It is shown that OWMA elements are good candidates for MIMO applications in laptops
