This research proposed microstrip circular patch antenna simulation at a working frequency 3500 MHz. The antenna has been designed using a Duroid RT5880 substrate with dielectric constant (εr) = 2.2, substrate thickness (h) = 1.575 mm, and tangent loss = 0.0009 with microstrip line feeding. The simulation result, return loss value obtained -26.385, VSWR value 1.09, gain value 7.64 dBi, total radiation efficiency value -0.6489 dB, and bandwidth value 72 MHz (3468.8 MHz – 3541.9 MHz).
