A Compact microstrip antenna with rectangular slotted radiating element has
been developed. Four slots have been introduced on the radiating element
with the use of a partial ground plane and a wideband response has been
obtained. The bandwidth of the proposed antenna is 1.7 GHz with a
percentage bandwidth of 71%. A low-cost dielectric (FR4_EPOXY) has been
considered in the development of the proposed antenna. The obtained
frequency band is from 1.9 GHz to 3.6 GHz. To investigate the robustness of
our modelled antenna the simulation process has been carried out using two
different solvers (Finite Element Method and Finite Integration Technique).
In addition, the designed antenna was realized and these results were
compared with those of the simulation. The proposed antenna is suitable for
many LTE bands {1, 3, 7… 38, 40} broadly deployed in European, South
American, Asian, and African countries, Wi-Fi (2.4 GHz), and WiMAX
technology (3.5 GHz).
