SMALL PRINTED MEANDER SYMMETRICAL AND ASYMMETRICAL ANTENNA PERFORMANCES, INCLUDING THE RF CABLE EFFECT, IN THE 315 MHz FREQUENCY BAND
An easily manufactured, reduced size, symmetrical printed meander dipole antenna for remote keyless entry (RKE) automotive applications in the 315 MHz frequency band is proposed. The efficiency and directionality of this symmetrical antenna is estimated and compared with the efficiency and directionality of an asymmetrical antenna. Numerical and experimental results are presented. © 2006 Wiley ...
متن کاملA Small Printed Quadrifilar Helical Antenna for BGAN/GPS Applications
This paper presents an element of a 2×2-element array antenna for Inmarsat BGAN/GPS applications. The element is an axial mode printed quadrifilar helical antenna that has been integrated with a compact feed network to provide sequential phase rotation for circular polarization (CP) radiation. The novel integrated lumped-element feed network is designed to provide a balanced RF power to the fou...
متن کاملDual-band Circularly Polarized Microstrip Antenna with Small Frequency Ratio
A compact single-feed dual-band circularly polarized (CP) microstrip antenna is evaluated numerically and experimentally. The dual-band performances with small frequency ratio (about 1 : 1.1) are achieved by a circular patch and a narrow annular-ring, which have small difference in radius. The CP characteristics are achieved by an unequal cross-slot embedded in the circular patch and two orthog...
متن کاملDesign and Implementation of a Compact Super-Wideband Printed Antipodal Antenna Using Fractal Elements
A compact printed fractal antipodal bow-tie antenna is designed and implemented to simultaneously cover the operations in the C, X, and Ku-bands. It is demonstrated that by addition of small fractal elements at the sides of hexagonal arms of the bow-tie, a wide operating frequency range of 3.3 to 19.1 GHz can be covered while antenna size is only 30×34×1.2 mm3. In order to match the antenna to ...
متن کاملStudy of a Printed Small Size Trisul Shape UWB Antenna for Indoor Communication
An ultra-wideband (UWB) antenna with a narrow frequency notch is presented. The antenna has been fabricated on a FR4 substrate and occupies an area of only 25 × 25 mm. Starting from a Circular planar patch exhibiting a VSWR smaller than 2.5 in the 3.5−10 GHz band, a frequency notch at 5.65 GHz is introduced by two open slots above the coplanar waveguide feeding. The measured return loss shows a...
