Microstrip patch Antenna Array for Wireless Design Applications

The patch antenna multiple wireless applications recently indicate great prospects in the application of various areas of micro-engineering. The rapid development of wireless communication systems requires antenna researchers to develop miniature broadband antennas with communication systems with high radiation efficiency The paper relates to calculating the resonant frequency of a microstrip antenna, this article presents a low-profile, broadband microstrip printed circuit board (PCB) antenna with a double U-slot. Triple-Band resonant modes can be realized by precise slot placement on the board. Antenna performance is improved by installing a gap in the ground plane. The proposed antenna is made in the form of a rectangular patch. As a substrate, a widely used material is used – fib regals FR4 brand, in which, in the frequency range of interest to us, the relative permittivity εr = 4.3. The dimensions of the antenna are 30×40×0.8 mm, such an antenna is easily and simply powered using an unbalanced microstrip line with a wave impedance of 50 ohms.
