Abstract, this letter frequency reconfigurable u slot microstrip patch antenna le slot machine mi hanno rovinato presents a Ka-band(26.5GHz-40GHz) microstrip patch antenna with pattern reconfigurable characteristic. The antenna is provided with five rectangular patches and four RF mems (microelectromechanical systems for RF circuits) switches. The central patch and other surrounding patches are connected by the switches. By changing the states of the switches, the antenna can achieve four radiation patterns and it is designed and simulated by using Ansoft hfss.

The antenna is provided with five rectangular patches and four RF mems (microelectromechanical systems for RF circuits) switches.In addition, the different states are operated at the same centre frequency of 35GHz and the gain of the main radiation direction is about 7.5dB.
