摘要： Circular microstrip patch antennas with discontinuities in their feed line is presented in this paper. The antennas are composed of a radiating patch, and step discontinuities are given in its feed lines to improve the performance. The three circular microstrip planar array antennas through various signal excitation lines are computationally designed, and PCB etched, and their performance is analyzed based on various feed lines. The proposed array antenna operates in the ISM band at 2.45 GHz. The HFSS is used to design and perform the simulations. A prototype of an antenna effective at 2.45 GHz has been PCB etched and verified for concept demonstration. S_(11) [dB] at 2.45 GHz is -21.143 dB for straight feed line, -22.0 dB for one step feed line, and -24.72 dB for two-step feed line. The computational and practical outcomes illustrate that the S_(11) [dB] is enhanced for circular microstrip patch array antennas with two-step feed lines. The simulated and measured scattering parameters and radiation patterns show that they are in good agreement.
