Design of Antennas with Small Dimensions for Medical Implant Applications in the Millimeter-Range

Abstract

In this paper, two single-feed microstrip patch antennas at (31.5 & 60 GHz) have been designed and optimized for medical applications. The crow search algorithm (CSA) is utilized  to optimize the antenna parameters. Our main idea in this paper was to improve the parameters of the microstrip antenna considering several limitations such as antenna dimensions, specific absorption rate, etc. The dielectric ranged from 1 to 3. In addition, the area is considered between 300 and 1500 square millimeters. The simulation results of the proposed method show that the design and optimization of the parameters of the antennas within the millimeter-wave band cut back the physical size of the antennas. Therefore, these antennas will be a good choice for medical applications.
