A reconfigurable patch antenna integrated by using RF-mircoelectromechanical system (MEMS) switches is presented. The proposed antenna radiates a right-hand circularly polarised wave at the selected dual frequencies (4.8 and 7.6 GHz) with a high frequency ratio (1.6:1). The switches are incorporated into the diagonally fed square patch for controlling the operation frequencies. The proposed antenna satisfies the 3 dB axial ratio criterion and has gain between 5–6 dBi at both operating frequencies.
