Abstract

In this project, inset fed type rectangular microstrip patch antenna is designed in CST Design Studio program; produced by printed circuit method on FR4 substrate which has 1.6 mm thickness, 4.3 electrical conductivity value, and measurements are made using nano VNA device with SMA connection in near 2.46 GHz center frequency. Four types of grounding methods with five measurements (two measurements with the first one) which are different from each other in the literature, have been tried on the antenna and the results from the nano VNA device are given. In the study, -27.5 dB (random, according to the author method), -22.5 dB (random, according to the default substrate dimension method), -13.8 dB (2 times of W, L method), -23.8 dB (6 times of h plus W, L method) and -27 dB (12 times of h plus W, L method) S11 values are obtained, respectively, according to the different dimensions of the ground, and the dimensions are shortened in each measurement. The middle frequency takes values between the frequencies of 2.44-2.48 GHz and remains on WLAN frequencies.
