Abstract
Microstrip Patch Antenna merupakan salah satu trobosan dalam bidang teknologi yang mampu membuat sebuah antena memiliki ukuran yang kecil. Dalam penelitian ini bertujuan membuat antena UWB melalui simulasi FDTD untuk mendapatkan parameter kerja antena yang sesuai dengan spesifikasinya mencakup nilai Parameter S11 kurang dari -10 dB dan nilai VSWR diantara 1 - 2. Yang kemudian di cetak menggunakan bahan FR-4 untuk substrat dengan konduktor tembaga. penentuan dimensi feedline CPW dengan melakukan perhitungan impedansi karakteristik 〖(Z〗_0) dan juga penentuan panjang patch yang digunakan, didapatkan feedline CPW (impedansi karakteristik Z0 = 50 Ω). Desain menggunakan bentuk Elliptical Patch dengan 3 variasi ground yakni berbentuk Rectangular, Following Patch, dan Half Circular. Dengan dimensi jari jari panjang (A) = 19.5 mm, jari jari Pendek = 15.5 mm, dengan feedline lebar (Wf) = 2 mm dan jarak gap (g) = 0.32 mm. Diperoleh hasil simulasi 3 antena dimana desain 3 dengan Half Circular Ground memiliki bandwidth yang paling lebar dengan lebar kerja 16.14 GHz, diikuti oleh desain 1 dengan rectangular ground yang terbagi menjadi 5 bandwidth dengan bandwidth terlebar di 2.97 GHz dan desain 2 dengan bandwidth terbagi menjadi 8 dengan yang paling lebar di 2.91 GHz.

Microstrip Patch Antenna is one of the breakthroughs in technology that allows antennas to have a compact size. This research aims to develop a UWB antenna through FDTD simulation to obtain the operational parameters of the antenna that meet its specifications, including an S11 parameter value below -10 dB and a VSWR value below 2. The antenna is then fabricated using FR-4 substrate with copper conductors. The feedline CPW dimensions are determined by calculating the characteristic impedance (Z0) and the length of the patch to be used, resulting in a CPW feedline with a characteristic impedance of 50 Ω. The design employs an Elliptical Patch with three variations of ground shapes: Rectangular, Following Patch, and Half Circular. The dimensions are as follows: major radius (A) = 19.5 mm, minor radius = 15.5 mm, feedline width (Wf) = 2 mm, and gap distance (g) = 0.32 mm. The simulation results of the three antennas show that design 3 with a Half Circular Ground has the widest bandwidth with a working width of 16.14 GHz, followed by design 1 with a rectangular ground which has five bandwidths, the widest being 2.97 GHz, and design 2 with eight bandwidths, the widest being 2.91 GHz.
