Wideband 4 by 4 Microstrip Antenna Array with H-Slot Coupling for Ka-Band LEO Satellite Communications
This paper presents the design, implementation, and measurement of a wideband 4x4 microstrip antenna array for Ka-band (27.5–31 GHz) Low Earth Orbit (LEO) satellite uplink applications. To address the bandwidth limitations of conventional microstrip antennas, a H-shaped slot coupled feeding mechanism is utilized in a s...
