MHO Shape Slot Microstrip Patch Antenna for X-Band

In a research work, MHO-shaped slotted microstrip patch antenna is proposed. An antenna proposed on Rogger duroid 5880 substrate with thickness of 0.79 mm and relative permittivity of 2.2 have a dielectric loss tangent of 0.0009. This antenna is composed of rectangular slots. There is HFSS software used to design and analysis gain, directivity, VSWR, radiation pattern, and return loss.
