Abstract:
The global communication tra c has shooted up to massive levels since the last two
decades. The burgeoning era of the computers and birth of the mighty Internet has
promoted the unmatched growth of communication products and services. Technology
advancement has created immense possibilities to enhance computational power and
made operating systems so powerful to run multiple applications together. The number
of mobile subscribers has increased manifold since the inception of mobile network and
the requirement of multi-band is on the rise. To solve the current scenario, scientists and
engineers have come up with the new developed network technologies and advancements
which can therefore contribute to the maximum utilization of the communication spec-
trum. The lack of a standard way of allocating spectrum protocol give rise to an issue
for hardware designers. Thus they face problem of either using individual devices for
every spectrum or a single standalone device that can support multiple bands. In order
for mass production to be feasible, it is economical to have a device that can operate
multiple frequencies together. Talking from a hardware perspective, there are largely
two ways to tackle this problem: 1. Number of single bands are Multiplexed. Each
single band is assigned for a di erent frequency range. 2. A single multiband RF device
is used Therefore coming up with a robust multi band design is the ultimate solution.
This dissertation presents a useful design that supports multi band operation focusing
on size reduction and wider band gap between two bands.
