Abstract: There has been and will be a constant development in the field of communication systems and telecommunication in the form of network designs, access technologies, and equipment. Today, most of the mobile users are in indoors environments such as buildings, metros, arenas etc. These users are becoming impossible to serve from outdoor base station antenna because of energy-effective building techniques, which have RF shielding properties. A solution to this is to move antenna closer to the users in the indoor environment. There is a need to find a cost effective and economical and environmental solution to this switch. Generally, a separate deployment for RAKEL, 2G, 3G and LTE each is done for indoor coverage. With the use of a Multi band antenna, all the above radio access technologies can be deployed while sharing hardware. This thesis investigates one such multi band antenna’s performance parameters for frequencies ranging from 380 MHz to 2700 MHz and provides a case study which analyses multiple deployed network locations and design where the antenna is deployed while serving RAKEL, 2G, 3G and LTE.
