1.6 mm3 FR-4 epoxy with relative permittivity 4.4. The substrate’s upper layer is composed of of two antennas which is connected to a common feed and the base layer is composed of ground plane. The designed antenna has return losses of -16dB, -27.8dB, and - 21.7dB at 1.9GHz, 2.45GHz, and 4GHz. Gain achieved at 2.45GHz was 3.8dB.
