Feeding Techniques

This paper presents a comparative analysis of textile antenna using different feeding techniques for Global Positioning System (GPS-L1) application. Textile materials which are commonly used in the wearable application has gained much attention due to the flexibility and conformability characteristic of the antenna. Nevertheless, the flexibility of this antenna will introduce the bending and stretching element to its physical structure that may degrades the performance. To ensure the maximum power transfer takes place takes place between the source and the antenna, a suitable feeding method must be identified. In this paper, the microstrip feedline technique and coaxial feeding technique will be studied comparatively using Felt textile material as the substrate with the relative permittivity, ?r of 1.098 and tangent loss, ? of 0.0395. It is attached to a copper tape which act as the conductive material with thickness of 0.035 mm. Using Computer Simulation Technology (CST) Microwave Studio software, the result will be analysed comparatively from the performance validation in return loss, gain, bandwidth, directivity and radiation pattern

Feeding Techniques

In this paper, the comparison of different feeding techniques for a patch antenna, at X frequency band, to evaluate its quantitative impact on the different antenna parameters is presented. When different feeding techniques are applied at the X band spectrum to improve the impedance matching the performance of various characteristics parameters such as radiation pattern, gain, beam width etc are influenced. To find how much these are influenced a comparative analysis is carried out and results are presented in this paper. For investigation purpose, the patch antenna and the various feeding techniques were designed on Roger (RT5880) substrate at 8 GHz resonating frequency.

In this research work, a Cylindrical Surrounding Patch Antenna (CSPA) with improved performance parameters based on inset feed method compared to other feed techniques has been proposed for 1.8 GHz applications. The designed and simulated CSPA is a rotary version of an initially designed Rectangular Planar Patch Antenna (RPPA). The RPPA is mounted on a cylindrical surface with radius (r) 10 mm which is an increased curvature for better -10 dB S-parameter (S11), impedance Band Width (BW), Voltage Standing Wave Ratio (VSWR), radiation pattern, and gain. The copper radiating patch has been conformed on the surface of the grounded flexible polyimide substrate with relative permittivity (εr) 3.5 and thickness (h) 1.6 mm at normalized input impedance of 50 Ω. Results for the RPPA and the proposed CSPA have been compared with existing designs in terms of antenna size, resonant frequency (fr), return loss (S11), and gain while taking cognizance of the feeding techniques. The S11, BW, VSWR, and gain are -12.784 dB, 28 MHz, 1.8, and 4.81 dBi respectively for the rectangular planar patch antenna and -35.571 dB, 66 MHz, 1.5, and 3.74 dBi, respectively for the cylindrical surrounding patch antenna.
