5.4 Conclusion
The important design issues of antennas and arrays in cellular phone
base stations have been addressed in this chapter from a systems point
of view for enhancing the performance and capacity of mobile commu-
nication systems. We presented the antenna designs, which have been
used to enhance the capacity of systems and maximize the usage of
transmitted power in cellular phone networks, from an antenna engi-
neering perspective.
