Abstract

In this article, a highly efficient on-body wireless communication antenna has presented. The proposed antenna is dual-band in nature. The two rectangular shaped vertex at the two sides of the triangle (situated at the middle) is responsible for the two resonances of the antenna. The proposed modified triangular shape antenna is fabricated on low cost, durable FR4 PCB substrate material with a permittivity er = 4.3. To solve the complications of the on-body wireless communications, antenna design is proposed with dual-band performance. The antenna has an efficient reflection coefficient at 400 MHz and 2.45 GHz with increased. Bandwidth. The antenna is fabricated using the RMIT University PCB fabrication facility. The radiation performance of the antenna in free air and in the near field of human tissue shows efficient performance. The measured results highly agree with the simulated result found in the simulation. The antenna is characterized in both free air and in the near field of the human body. No change is found when the antenna is operating near the human body. The specific absorption rate is also calculated to achieve an operational design in the near field of the human body. The proposed antenna is an excellent choice for on-body communication system due to its dual-frequency operation along with the increased directivity performance than the literature..
