The two related feeding techniques, namely, the L-shaped probe and meandering probe (M-probe), for broadening the bandwidth of patch antenna are reviewed. The L-probe has a simple structure and wide bandwidth whereas the M-probe has low cross polarization and a symmetric radiation pattern within the operating frequencies. Design guidelines of the two kinds of patch antennas for Wi-Fi applications are presented. All the impedance bandwidths of the antennas were optimized to standing wave ratio (SWR) less than 1.5. The performance of the patch antennas with different patch height and aspect ratio is demonstrated. The performance of a wide M-probe fed patch antenna that has an impedance bandwidth of around 44% is presented. Finally, a review of various designs for different applications is discussed.
