In general, disease patterns are usually random or scattered. Your browning appears to be in a pattern. There may be several reasons for the browning but we cannot say for sure. We do not know how your turf is managed. If you planted a contractors mix of different species some of the grasses may be dying out. Also, Some grass species can go dormant at different rates during hot, dry weather.
Brown patch is a summertime disease that affects tall fescue, rye grass but not usually bluegrass. This may have affected other grass species in your turf. See our website for more information
You may need to do some seeding this fall if the turf does not recover.
