Preeti Singh, one of the way to fix a topic is, you pl. look Transaction on IEEE Antenna and propagation December month, at its last page it gives the topic names published in entire year. from this you may know what are the current topic on which work have been carried out. Look all the papers of you interested, like this do the observation for last eight years. Doing this you will have a good idea about the current lavel of technology on your interested topic. Take the copy of all the papers of you interest, study and look what is an extra innovation you can add. this would be one of the honest way to fix a new research topic. This I suggest to all the students.
Similar search cane be carried out on other publications like on line journals but careful for choosing reputed one. This is because meany online journals are floating only with their commercial motive not the technical quality.
Hope this note may give you a good start.
Microstrip antennas are an attractive area of research due to their exceptional properties like low-slung profile, ease of construction, and compatibility with printed circuit board (PCB) technology. Here are some possible PhD research topics on microstrip antennas that you may consider:
1. Microstrip antennas for evolving applications: The field of wireless communication is constantly emerging, with new applications ever evolving. You could focus attention on designing microstrip antennas for specific applications such as:
a. Metamaterial-inspired microstrip antennas: Metamaterials are preciously engineered resources with properties not originate, in nature. By incorporating metamaterials into microstrip antenna designs, researchers can attain innovative functionalities such as improved gain, miniaturization, and polarization control.
b. Microstrip antennas for mmWave and THz applications: The millimetre-wave (mmWave) and terahertz (THz) bands offer massive potential for emerging wireless communication systems. However, manipulative efficient antennas for these frequencies is challenging. Your research could focus on developing microstrip antennas that function effectively at mmWave and THz frequencies.
2. Innovative design and analysis techniques for microstrip antennas: With the advancements in computational tools and electromagnetic modelling techniques, new potentials are evolving for microstrip antenna design and analysis. You could explore the use of these techniques for:
a. Multi-parameter optimization: Optimizing microstrip antenna design for manifold performance parameters instantaneously is a complex challenge. You could advance innovative optimization algorithms to address this challenge.
b. High-performance computation for large-scale replications: Simulating complex microstrip antenna structures can be computationally expensive. You could explore the use of high-performance computing techniques to accelerate the simulation process.
