Microstrip antennas are compact-shaped antennas that can accommodate general antenna capabilities, with the advantage of being easy to fabricate and cost-effective in production. However, they have some drawbacks, one of which is their small antenna bandwidth. By using the Deflected Ground Structure (DGS) method, it becomes possible to enhance the antenna's performance with a wider bandwidth. The author is currently researching the use of this method for ultra-wideband applications. Ultra-wideband refers to antennas with a minimum bandwidth of 500

MHz, which presents a challenge when implementing microstrip antennas.

Results of the five microstrip antenna models using the defected ground structure (DGS) method were obtained. All five antennas meet the specifications for Ultra Wide-Band (UWB) Frequency, with the largest return loss value of -29.93 observed in model D at a frequency of 9.2 GHz. This model also exhibits the widest bandwidth, which amounts to 9.17 GHz, ranging from 3 to 12.17 GHz. The Voltage Standing Wave Ratio (VSWR) of all five antennas also complies with the specified requirements, with the highest value found in models A and D, both at 1.09 at a frequency of 8.3 GHz. Furthermore, all antennas have a gain greater than 0, with the highest gain of 6.05 dB observed in antenna model B at a frequency of 10.6 GHz
