چکیده

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 Periodicals, Inc. Microwave Opt Technol Lett 48: 1828–1833, 2006; Published online in Wiley InterScience (www.interscience.wiley.com).

Slot Loaded Microstrip Antenna for GPS , Wi - Fi , and WiMAX Applications Survey

A tri-band slot loaded microstrip antenna is proposed. The tri-band characteristics of antenna are achieved by incorporating a combination of symmetrical Y-shaped and asymmetrical U-shaped slot. The Y-shaped slot is placed symmetrically where as U-shaped slot is placed asymmetrically to the center of the patch to achieve the desired tri-band characteristics. The return loss characteristics show...
