In this paper, to estimate the Wi-Fi throughput between smart TV and AP (Access Point), the novel methodology is realized by modeling of Wi-Fi 802.11n communication considered real system characteristics. Also, analysis of throughput performance of digital TV by noise effect using the simulation methodology is presented. This result shows very good agreement between measurement and the proposed methodology.
This paper presents a novel robust design method for a mobile antenna with a metal frame. In order to improve the robustness of the antenna against the tolerance occurred in the fabrication process, the proposed robust design method combines genetical swarm optimization with an orthogonal array. The robustness of the optimum model is better than that of the conventional model by 21%.
In this article, a capsule antenna used in an ingestible medical device is proposed. To achieve miniaturization and a wide bandwidth, an inverted‐F antenna with a meandered strip line was used. The antenna performance in a human voxel model is analyzed through simulation, and the performance of the fabricated antenna is verified by comparing the measured data with that of the simulation, when the...
In this paper, an implantable planar inverted-F antenna (PIFA) for an artificial cardiac pacemaker is proposed. The antenna has a simple structure with a low profile and is placed on the top side of the pacemaker. The dimension of the pacemaker system, including the antenna element, is 42 mm × 43.6 mm × 11 mm. When the antenna is embedded in pig tissue, −10 dB impedance bandwidth of the antenna is...
Circulary-polarized (CP) planar antennas have been received much attention for mobile wireless communication applications since they are not only able to reduce the multipath effects but also provide flexibility for transceivers [1]. CP microstrip antennas are widely used but they are required to have broadband, small size, light weight, and low profile characteristics [2]. However, conventional CP...
The applications of a wireless body area network (WBAN) have been expending in medical services, police and military agencies, sports training, entertainment, wearable computing, and so on [1]. In WBAN applications, antennas are required to have a small size, low human body effect and low specific absorption ratio (SAR) [2]. The human body has a high dielectric constant with a high loss tangent and...
In this paper, a patch antenna for 2.45 GHz ISM (Industrial Scientific Medical) band Wireless Body Area Network (WBAN) applications is proposed. To enhance specific absorption rate (SAR), an electrically coupled LC resonator is introduced. The overall dimensions of the proposed antenna are 54 × 45 × 2.4 mm3 and it has a gain of over 1 dBi for the entire 2.45 GHz ISM band. The proposed antenna has...
The electromagnetic characteristics of FCEVs(fuel cell electric vehicles) are much different from the existing combustion engine cars as well as hybrid, plug-in-hybrid, and pure electric vehicles due to the high voltage/current generated by a fuel cell stack which uses a compressed hydrogen gas reacted with oxygen. To operate fuel cell stack efficiently, BOP(Balance of Plant) is essential. BOP systems...
A multiband internal antenna that operates over WiBro, WLAN, WiMax, and S-DMB frequency bands is proposed. The antenna consists of two-pronged element and two stubs. The measured return loss of the designed antenna over the frequency band of interest was greater than 10 dB. Good return loss and radiation pattern characteristics were obtained in the desired frequency band.
In this paper, an internal planar monopole antenna for use in WUSB dongle application is proposed. The antenna, suitable for WUSB dongle application, occupies a compact area of 20 mm times 10 mm times 1 mm. The planar antenna consists of a modified meander-strip and an inverted L-strip. The antenna elements are printed on the top and bottom sides of substrate, respectively. The impedance bandwidth...
In this paper, a planar inverted-F antenna with wideband characteristic is proposed for GSM850/DCS1800/DCS1900/EMT200/WLAN/DMB services at the same time. The proposed antenna is composed of a main patch with a pair of slant slits and L-shaped patch and has total volume of 15 times 45 times 8 mm3. To achieve triple band operation, the length and width of a slant slit 1 on the main patch are optimized...
