Pet Substrate

In the proposed paper, a flexible Yagi Dipole Antenna based on PET Substrate is designed for the RF system-on-package (RF SOP) applications. RF antenna as a smart sensor is designed on a Flexible substrate Polyethylene Terephtalate (PET). It is the more popular and universally accepted thermoplastic polymer belonging to the family of the polyester. It is generally employed in textiles, thermoforming packaging along with glass fibers. In the proposed design Coplanar Strip line (CPS) is used as a feeder and the RF antenna is a Yagi dipole Antenna with a single driven element i.e. director, and a single reflecting element i.e. reflector. It is a linearly polarized antenna which means it radiates in a single direction. The antenna is designed at a resonating frequency of 5 GHz with a return loss of -23 dB. Simulations of the flexible PET based Yagi Dipole Antenna is carried out by using CST Studio Suite software for Return loss, Radiation plot with varied curvatures. The results for designed flexible Yagi Dipole Antenna imprinted with a PET substrate for portable wireless electronics are analyzed.

Antenna Model

Wireless Fidelity (WiFi) devices are often used to access the internet network, both for working and in information searching. Accessing the internet can be administered anywhere provided that the area is within the WiFi devices range. A WiFi device uses 2.4 GHz and 5 GHz operating frequencies. There were several methods employed in the previous studies so that an antenna design could work in two different frequencies, i.e., winding bowtie method, Sierpinski method, and double-circular method. This paper employed a simple method, the slit method. The objective of this paper is to discover a simple antenna model that works on 2.4 GHz and 5 GHz frequencies. This paper employed a square patch microstrip antenna with a slit method. The dimensions of the designed square patch microstrip antenna were 42.03 mm × 27.13 mm × 0.035 mm. The antenna worked at 2.4 GHz and 5 GHz frequencies. The obtained simulation results after the optimization showed that the square patch microstrip antenna using the slit method acquired a value of S11 (return loss) of -10.15 dB at a frequency of 2.4 GHz and -37.315 dB at a frequency of 5 GHz.

Different Types

In this paper, leaf shape textile antenna in ISM band has been chosen to study. The operating frequency of the dipole antenna is 2.45GHz. The effect of conductive threads with three different types of sewing has been analysed. The first type of sewing leaf shape dipole antenna is to stitch around itself and embroidered into a fleece fabric with circular follow by vertical and horizontal stitch respectively. From measured return loss, the antenna with circular stitch shows better performances with optimum resonances compared with the two types of stitching. The measured results confirm that the circular stitch is more suitable for leaf shape dipole antenna design. Thus it can be concluded that different stitch gives different results for leaf shape dipole antenna.

A highly stretchable small-size 5 GHz dipole antenna is presented for wearable and mobile applications. A stretchable dipole antenna was fabricated using conductive polymer composite material composed of Ag flake filler and polyester binder. The dipole antenna was printed on a stretchable polyurethane substrate using a simple and inexpensive screen-printing technique. The stretchability and durability of the dipole antenna were evaluated by the stretching and cyclic stretching tests. The stretchable dipole antenna showed excellent stretchability and RF performances up to a tensile strain of 25%. The stretchable dipole antenna also exhibited outstanding mechanical durability in the 10,000-cycle cyclic stretching endurance tests.

Microstrip Feed

AbstractThis paper presents the application of new high permittivity and low loss glass material for antennas. This glass material is transparent. A very simple rectangular dielectric resonator antenna is designed first with a simple microstrip feeding line. In order to widen the bandwidth, the feed of the design is modified by forming a T-shaped feeding. This new design enhanced the bandwidth range to cover the WLAN 5 GHz band completely. The dielectric resonator antenna cut into precise dimensions is placed on the modified microstrip feed line. The design is simple and easy to manufacture and also very compact in size of only 36 × 28 mm. A −10 dB impedance bandwidth of 18% has been achieved, which covers the frequency range from 5.15 GHz to 5.95 GHz. Simulations of the measured return loss and radiation patterns are presented and discussed.
