2.4 GHz Operational PSI-Shaped Patch Antenna Design For Multi Purpose Applications

With the evolution of communication systems and their methodologies, the significance of designing various types of antennae has increased to suit the different necessities. While some antennas, especially the substrate-integrated antennas are hard to optimize, the microstrip patch antennas are easy to design and optimize. Besides, providing an economic advantage, it also delivers higher efficiencies in terms of radiation and gain, making it appropriate for communication-based applications. The concerned work proposes a psi-shaped optimized antenna that is capable of scanning and receiving the 2.4 GHz resonant frequency for applications like radio-frequency (RF) energy harvester systems (RFEHS), radio-frequency identification (RFID) and wireless local area network (WLAN) communications. The structure has been tested with an inset feeding technique and the substrate used is arlon with differential conductor and cover layer elements. The entire design and simulation have been carried out in advanced design system (ADS) layout and momentum microwave electromagnetic (EM) mode. The designed psi-shaped antenna is able to produce a maximum gain of 5.47 dBi with a radiation efficiency of 70.39%, making it suitable for the aforesaid applications. A software-based prototype simulation has also been carried out to find the effectiveness of the proposed antenna.
