Though reconfigurable antennas are not new technology but still there is a lot of research scope in this area to meet new emerging technologies need. Optimizing the reconfigurable antenna design parameters for wireless communications (like 5G) at different frequency bands is one potential area for research. Phased array and reconfigurable antenna will be used in 5G. The pattern reconfigurable antenna has advantages such as maximum pattern diversity and optimum switching circuits to realize 5G reconfigurable antennas. Reconfigurable antenna designs based on smart materials such as ferrites and liquid crystals is another good area for research. Phase change materials are also extensively used for a reconfigurable antenna. These have advantages over ferrite and liquid crystals as they have less losses, high reliability, and excellent linearity. Also, their biasing can happen remotely, so their biasing network does not affect the performance of the antenna, which is a big advantage compared to other methodologies.
You can check wearable antenna designing topic. NBIoT. 5G and also biomedical health care wearable antenna topics are very interesting.
Hi there,
Reconfigurable antennas research topic is good. But suggest you to aim higher frequencies such as for Mm-wave technologies. That would be good and u come out with really nice research.
Two things: Equipment for fabrication and equipment for measurement. Both are costly for mm wave. If you are doing modelling based on maths, or working on numerical methods, that is fine - else I would not recommend to venture into the mm wave.
