This paper presents the design and modeling of deformations of textile antenna wireless body area network (WBAN) applications. The performance of a compact planar flexible antenna is analyzed in terms of reflection coefficient and radiation pattern under bending and crumpling conditions. Unlike in the existing works, the bending condition in this work carried out in two different axes, x-axis and...
This work investigates the suitability of a flexible Minkowski-like pre-fractal antenna (MLPF) for application in the Very High Frequency (VHF) Land and Mobile Radio (LMR) frequency bands (136-174 MHz). The proposed center-fed, third iteration antenna has been manufactured using both copper tape and Shield It Super, a conductive textile. It has been tested on four types of ground plane, i.e. rectangular,...
Meander line antenna with parasitic element was investigated. It has been designed to operate at 2.4-GHz which are specified by IEEE 802.11b/g for WLAN. The antenna designed has been done for planar type. Microwave Studio SCT Microwave Office software is used for simulation designed process. The antenna is fabricated on a double-sided FR-4 printed circuit board using an etching technique. Then the...
This work investigates the design of a flexible Minkowski fractal antenna. Two potential materials are included for examination - conductive copper tape and ShieldIt conductive textile. Both are designed and simulated to achieve a satisfactory resonance at the Very High Frequency (VHF) band for Land Mobile Radio (LMR) application through proper structure segmentation and iteration. Optimization concludes...
Due to their popularity, antennas implemented on conductive textiles have been widely investigated. Prototypes of full-textile antennas are also usually pre-investigated using conductive foils, which is more homogeneous and provides better mechanical consistency. However, in today's practical applications, various electronic devices are still implemented on low-cost FR4 boards, popular in printed...
This paper present development in relation to a wideband antenna comprising a disk antenna and a plurality of circular split ring resonators coupled with a high dielectric ring. Using slotted resonators together with optimized air gap in order to achieve elevated bandwidth comes with minor setbacks: moderate gain and directivity, side coupling effect and unbalance electrical field strength and intensity...
This paper describes the design and simulation of Sierpinski Carpet Fractal Planar Inverted F Antenna (PIFA) for WLAN and HiperLAN applications. Simulation of antenna is carried out using CST software; on a FR4 board with a substrate thickness of 1.6 mm and relative permittivity of 4.7. The antenna achieved satisfactory 10-dB impedance bandwidths, between the frequencies of 2341-2812 MHz and 5360-6154...
A novel Fractal planar inverted F antenna F-PIFA based on the self affinity design is presented in this paper. The procedure for designing a Fractal Planar Inverted F Antenna is explained and the 2nd iteration of Sierpinski Carpet is chosen as an antenna for mobile phones. The F-PIFA has a total dimension of 27 mm × 27 mm and is designed and optimized to receive GSM (Global System for Mobile Communication)...
Bandwidth characteristics of a wearable antenna are one of the major factors in determining its usability on the human body. In this work, a novel structure is proposed to achieve a large bandwidth, in order to avoid serious antenna reflection coefficient detuning when placed in proximity of the body. The proposed structure is designed based on a simple structure, in order to provide practicality...
