Abstract
This paper presents designing of a conformal antenna using a number of microstrip patches in C band frequency range 4 GHz to 8 GHz. The type of microstrip C-band antenna was chosen because it is suitable for use on portable surveillance radar systems. Single element patches antenna with a carved slit is used to obtain a horizontal polarization. In this paper, an microstrip patch antenna C-band frequency for 3-dimensional radar application was designed using CST Studio Suite 2018. The antenna operates at frequency 5.6 GHz, with 40.55 x 22.65 mm dimension using substrate Rogers RO-4350B (lossy) with thickness 1. 524 mm and relative permittivity 3.66. The bandwidth obtained from the simulation is 200 MHz, the return loss values below -20 dB, VSWR less than 2, 5.6 dB gain, and has directional radiation pattern.
