E-Shaped Wideband Conformal Antenna

A compact wideband antenna with cylindrical conformal geometry is proposed . The radiating element of this antenna consists of an Eshaped patch that assumes a conformal orientation relative to the cylindrical surface in order to yield maximum bandwidth. The antenna is fed by waveguide feeding connected to the radiating patch at the longer side Radiation properties of the proposed including far-field patterns, axialratio, directivity, input impedance and voltage standing waveratio (VSWR), are studied simulating through HFSS (High Frequency Simulation Software).Simulation results are in good agreement, nearly equal Eand H-plane far-field patterns withhigh degree of axial symmetry over a bandwidth of more than 50%. Also, over a bandwidth of about 24% the axial ratio remains below 3 dB. The compact size and ultra wideband performance of this antenna make it advantageous for highspeed wireless communication systems and avionics.
