While posted as an Assistant Professor at The ICFAI University, I enrolled myself for Doctor of Philosophy (ECE) in the same institute. After consulting my guide and keeping in mind my previous research as well as status in J&K, I decided to go for 5G and proceed with an antenna as my research work. The fifth generation (5G) has better specifications, that is, high data transfer rates (up to 1 Gbps with latency less than 1 m/s), large bandwidth, etc. With these properties, one can send large files and have video calls without buffering. One of the main highlights of the 5G is the real-time control of devices, that is, the Internet of Things. Now, I have to analyze the specifications needed for 5G antenna provided by the Federal Communication Commission as well as the International Telecommunication Union, such as frequency bands, data transfer rates, etc. Designing an antenna is not a big deal, but making an efficient antenna that supports high data transfer
rates, high bandwidth, and low
power consumption, and is
reliable may take time. These characteristics still are not
satisfactory since the designed
antenna must be of small
size as it has to be integrated
into mobile devices. One day
during my hectic schedule,
while studying the research
papers, I found the application
of optimizing techniques such
as thinning and tapering as well
as algorithms such as genetic,
immune algorithms, etc., to
antennas. So I thought of using
these techniques in my antenna,
which was an array of huge
elements. By further reviewing
research papers, I concluded
that although the algorithms and optimization were applied to the antenna, they could not be
applied to large arrays containing numerous elements and that too for 5G. By considering the optimization techniques and algorithms, I can reduce the number of elements that will decrease power consumption without disturbing other characteristics of the array antenna.
Recently, fiber-optic services have been introduced, but since the services are expensive, everyone cannot afford that. The motive of my study is to design and fabricate the array antenna with distinct feeding techniques, implemented with the use of optimization approach and algorithms, and to assess their performance in terms of gain, sidelobe level, bandwidth, radiation pattern, and directivity. My planned work needs a thorough study of antenna arrays, feeding network, and optimization techniques to execute the same with the formulas and achieve the dimensions of both element as well as feeding network,
but this is not the end; I have to learn simulation software. The simulation software is computer simulation technology, which is the best tool for antenna designing. At the same point of time, my inner voice has a line with me “Hey, when you are going to grasp this new tool, look at your time table, you are already messed with these slots!!”. Bypassing these thoughts, in a very stipulated time, by hook or crook I attained the knowledge and started designing. The proposed study needs distinguish styles associated with the patch, such as rotation, slotting, conformal technology, etc., along with the feeding networks. My very first
and basic design was published, which can be a good candidate of the 5G.
