New Selective Dual Band Microstrip Patch Antenna for WLAN

“…In this paper, the probe feed position choice is based on the idea proposed in [5] where the probe feed impedance of a rectangular segment is obtained from the coupling impedance between the probe feed and another port. This impedance is then simplified & used to locate the required position to obtain matching at the required two frequencies.…”
