Circular microstrip antenna4/6/2024 From the simulation results obtained reflection coefficient value of -20.02 dB and VSWR of 1.22 at the working frequency of 2300 MHz. Circular polarization can be obtained by cutting the edge of a rectangular patch antenna with an angle of 45°. Gain of antenna can be optimized by increasing the number of elements in the array of the antenna. The proposed antenna designed using FR-4 substrate with (ɛr) = 4.3, substrate thickness (h) of 1.6 mm and loss tangent (tan δ) of 0.0265. Gain of antenna is optimized by using an array method with 4 elements arranged in plannar using feed line of 50 Ohm, 100 Ohm and 70.7 Ohm.
