The present invention relates to a miniature original tetra-generations patch antenna with rectangular slots at low cost, and dedicated to the new generation of mobile telephony by covering the frequency bands of 900MHz, 1800MHz, 2100MHz and 2600MHz. The Modeling and simulation of the basic model are performed using the Ansoft HFSS simulator employing finite element method (FEM). This study allowed us to determine the reflection coefficient, the voltage standing wave ratio (VSWR), the omnidirectional radiation and the bandwidth. With this antenna, we obtained new results from the GSM thermal effect on the human head and hand. With this in mind, a new, simple and miniaturized quadri-band antenna in patch technology meeting the standards of dosimetry and temperature for mobile phone applications is designed and proposed.
