A design of printed antenna with compact size for IEEE 802.11 a/b/g application is proposed. The antenna is printed on an FR4 substrate of thickness 1.6 mm and dielectric constant of 4.4. The size of the design is with the overall dimensions of 40 × 5 mm2 and that of an antenna area is 14 × 5 mm2. The antenna consists of a T-shaped metal strip fed by 50-ohm mini-coaxial cable on the front side of...
A novel dual-polarization array antenna based on substrate integrated waveguide(SIW) terminal slot antenna is presented. Unit cell of the array antenna is a T-shaped combination consisted by a couple of substrate integrated waveguide terminal slot antenna, which resulted in higher polarized-isolation and wider bandwidth. The radiation character of the unite cell is also simulated and the manufactured...
Development of wireless technologies pushes for more accurate and more consistent EMC measurements. Antenna cross polarization is found to be a main contributor to the measurement errors. In this paper, full-wave analysis of E-field distribution of various slotlines is presented, which reveals that the bilateral tapered slot antenna has the widest impedance bandwidth and the lowest cross-polarization...
In this work we investigate a slot bow-tie antenna fabricated using wet-etching technique on a 5mil laminate having a low dielectric constant (εr = 2.2). The planer antenna is aiming to operate, linearly polarized, in the range of 85–95 GHz. The return-loss measurements show acceptable agreement with FEM simulations. The simulated radiation patterns and Co/Cross polar patterns are also presented.
