 The Yagi utaplanar antenna is a type of antenna commonly found in small high-tech devices. It is designed to be smaller and easier to integrate into these devices, but still provide good performance. To improve the performance of the antenna, several modifications were made including changing the number of directors, adding additional conductive elements, and using different dielectric materials. These changes resulted in a 10% increase in bandwidth and a 30% increase in gain, achieving a peak value of 4.84 dBi. Additionally, the antenna was tested for compliance with safety regulations regarding human exposure to electromagnetic fields. The results showed that the antenna's maximum electric field limit was 0.349 V-slash-M, and the maximum magnetic field value was 28.441 V-slash-M, both of which are above the limits set by the International Commission on Non-Ionizing Radiation Protection, ICNIRP. Therefore, the antenna should not be placed too close to the human body, or some form of protection should be provided.
