This paper presents a new, small, compact microstrip antenna, designed for modern uses, particularly in IoT and mobile technologies. The antenna's originality lies in a cross-shaped structure with parallelogram extensions, in which several slots are cut, acting on the electromagnetic behavior. Constructed on a FR4 substrate measuring 40  ×  30 mm2 and 1.6 mm thick, it can be easily integrated into compact devices. Results obtained using HFSS reveal stable operation over a wide frequency band from 3 to 6.25 GHz. The antenna boasts a Peak Gain of 6.5 dBi and a very satisfactory radiation efficiency of 99%. This performance underlines its potential in embedded systems, where every millimeter and every decibel counts.

摘要

This paper presents a new, small, compact microstrip antenna, designed for modern uses, particularly in IoT and mobile technologies. The antenna's originality lies in a cross-shaped structure with parallelogram extensions, in which several slots are cut, acting on the electromagnetic behavior. Constructed on a FR4 substrate measuring 40  ×  30 mm2 and 1.6 mm thick, it can be easily integrated into compact devices. Results obtained using HFSS reveal stable operation over a wide frequency band from 3 to 6.25 GHz. The antenna boasts a Peak Gain of 6.5 dBi and a very satisfactory radiation efficiency of 99%. This performance underlines its potential in embedded systems, where every millimeter and every decibel counts.
