Dual-band and low cross-polarisation printed dipole antenna with L-slot and tapered structure for WLAN applications

A Dual-Band Slotted Trapezoidal Inverted-F Antenna for Indoor Wlan Communications

“…As can be seen, its total size is 47.0 × 35.0 × 4.5 mm 3 , which is much thinner than that (43 × 26 × 12 mm 3 ) of a 2.4/5.8 GHz dual-band directional antenna proposed in [8] for RFID reader applications, and much more compact than that (57 × 57 × 21 mm 3 ) of a 2.5-4.8 GHz slot antenna designed for WLAN systems in [10]. Table 1.…”

“…For indoor wireless access points or point-to-point communications, however, it is often required that the antenna is somewhat directional to allow the installation of the antenna against a wall or on a ceiling surface [6][7][8]. Slotted structures are often used to realize multi-band performance [9][10][11], in particular for dual-band patches [12,13]. One resonance is due to the fundamental mode of the main patch, while the currents along slot edges introduce an additional resonance.…”

Compact dual-band C-shaped printed antenna for WLAN applications

“…In [1][2][3], the desired dual bands are formed by two meandered strip. In [4][5][6], the multiband performance is achieved with the use of slot structures. Many other planar antennas with different configurations are reported for WLAN applications in [7,8].…”

A Hybrid of T-Dipole and Quasi-Yagi Antenna for Dual-band WLAN Access Point

“…Therefore, the antenna for WLAN AP requires not only dualband operation but also an insignificant back-radiation. Several antennas [1]- [3] were reported for dual-band applications, including the printed dipole antennas [1], [2] or slot-monopole antenna [3]. However, these antennas have omni-directional radiation patterns, hence cannot prevent the radiated wave from propagating to undesired directions.…”
