Various promising multiband antenna designs for portable WLAN devices are found in the literature вЂ“. For instance, WLAN systems in the USA and Europe have started to operate in the 5.2 GHz (5.15-5.35 GHz), 5.6 GHz (5.47-5.725 GHz), and ISM 5.8 GHz (5.725-5.850) bands, in addition to the traditional ISM 2.4 GHz (2.4-2.4835 GHz) band. In order to overcome these effects and achieve higher data transfer rates, which is required by some modern applications such as video streaming and conferencing, many of the mentioned wireless communication systems have adopted additional operating bands at higher frequencies. Additionally, the availability of smaller and cheaper devices has attracted an increasing number of users in recent times.Д«ecause of the great and rapid popularization of mobile phone, wireless local area network (WLAN), and wireless personal area network (WPAN) systems, the use of the electromagnetic spectrum in the lower microwave frequency range, notably in the L and S bands, has become increasingly intense, favoring the occurrence of spectrum saturation and electromagnetic interference, which deteriorate the communication performance. In the last years, technology advances in the areas of microelectronics, telecommunications, and computation have enabled the development of several wireless communication systems, providing a great variety of services and applications. Multiband Antennas Portable-Device Antennas Printed Monopole Antennas The fabricated prototype of the proposed printed monopole antenna has overall dimensions of 22 Г— 48 Г— 1.6 mm 3, and the measured 10-dB return-loss bands exhibited by the antenna are 2149-2660 MHz and 5120-6035 MHz. A parametric study on several geometrical dimensions of the antenna is carried out in order to analyze their influence on the antenna performance. An additional open-ended strip connected to the radiator is used to adjust the antenna input impedance in the upper operation band.

The folded strip radiator interacts with the parasitic strips, which are connected to the ground plane, in such a way as to produce the resonant modes that originate the radiation bands of the antenna.

It is composed of a folded strip radiator and two parasitic strips printed on a partially grounded substrate. This antenna is compact, thin, lightweight, easy to manufacture, and suitable for portable devices. This paper presents a novel printed monopole antenna for quad-band operation in four WLAN bands: ISM 2.4 GHz, 5.2 GHz, 5.6 GHz, and ISM 5.8 GHz.
