This paper present a comparative study between two works proposed for microstrip patch antenna dual band operations. The comparison is made between a dual-band planar antenna with a compact radiator for 2.4/5.2/5.8-GHz Wireless Local Area Network (WLAN) applications and a printed circular microstrip patch antenna with a four rectangular shape strip and co planar rectangular ground plane antenna. The comparative analysis between these two antennas consist of following parameters such as dimensions, bandwidth, gain, return loss, directivity etc.

A dual band F-shaped printed mono-pole antenna (USB dongle) with two meandered strips is proposed and tested. The two strips that resonating at 2.45 GHz and 5.2 GHz have uniform and fixed width of 0.5 mm. A thin layer of 0.8 mm thickness FR4 substrate (permittivity =4.4, loss tangent=0.0245) which is economically cheap is used for the unit fabrication.  The two resonant modes will best support Bluetooth (BT) and WLAN (Wireless Local Area Network) having enough supportive bandwidth which is defined by -10dB reflection coefficient. The proposed unit is low profile, compact and simple to fabricate. The whole unit that has an overall size of (0.8mm x 10 mm x 40 mm) is efficient for having 97% and 94 % total radiation efficiency at both operating frequencies respectively. Through applying different simulation scenarios to the unit such as varying the feeding location and changes in the strips length, it has been revealed that the antennas is sensitive and reactive. The proposed antenna has provided good performance and Omni-directional radiation pattern. Good matching between the simulated and measured reflection coefficient results for the antenna prototype has been achieved.

A dual-band folded-coupling planar inverted-F antenna (FC-PIFA) is presented in this paper. By using the folded-coupling technique, the proposed antenna provides two distinct impedance bandwidths of 159 MHz (about 6.5% centered at 2.45 GHz) and 1512 MHz (about 27.5% centered at 5.5 GHz), which cover the required bandwidths for the 2.4/5 GHz wireless local area network (WLAN) communications. Moreover, the antenna shows a low profile of 5 mm and a small length of 20.5 mm in radiating area, making it easy to be installed in the casing of wireless handheld devices and laptops. Details of the design procedures and experimental results are discussed.

Abstract This paper presents the design, simulation and fabrication of a miniaturized wearable dual-band antenna on a semi-flex substrate; she is operable at 2.45/5.8 GHz for wireless local area network applications. The electrical and radiation characteristics of this proposed antenna were obtained by means of a technical of insertion of a slot to tune the operating frequencies. To study the impact of the electromagnetic radiation of the structure of the human body, it is necessary to minimize the back radiation towards the user. Therefore, in this work, a multi-band artificial magnetic conductor (AMC) was placed directly above a dual-band planar inverted F antenna to achieve a miniaturization with excellent radiation performance. The simulation results were designed and simulated using Studio commercial software (CST). A good agreement was achieved between the results of simulation and the experimental. The Comparison of measurement results indicates that the gain improved from 1,84 dB to 3,8 dB, in the lower band, and from 2,4 dB to 4,1 in the upper band, when the antenna is backed by the AMC plane. The front-to-back ratio of the AMC backed PIFA antenna was also enhanced. Then, to ensure that the proposed AMC is harmless to the human body, this prototype was placed on three-layer human tissue cubic model. It was observed that the through inclusion of plane AMC, the peak specific absorption rate (SAR) decreased to 1,45 and 1,1 W/kg at 2,45 and 5.8 GHz, respectively (a reduction of around 3,7 W/kg, compared with an antenna without (AMC).

The CPW-fed is used to enhance the bandwidth and to reduce the return loss of the antenna. The importance of different design parameters like current distribution, S-parameter, gain, and radiation pattern are studied. The results of the proposed antenna are useful for WLAN Application.
