Abstract : In this paper, conformal rhombic microstrip patch antenna for X-band application (8GHz to 12GHz) is depicted using software analysis. The key benefits and shortcomings of a conformal microstrip patch antenna are being familiarized through this paper. Here we are designing non-planar antenna with cylindrical surface having radius of curvatures R1=15mm, R2=30mm and R3=45mm and comparison of planar and non-planar antenna design will be undertaken. Microstrip feedline technique is utilised for ease of impedance matching. The antenna designing and analysis is carried out on High Frequency Structure Simulator (HFSS). The consequences of bending due to conformability of patch over various cylindrical surfaces are calculated. Radiation pattern (E-field and H field), reflection coefficient (S11), peak gain (dB) and antenna efficiency are examined as a function of radius.
