This paper proposes a feeding method for four-arm sinuous antenna, which is realized by using microstrip printed board welded on metal pyramid. It is an effective way to solve the problem of input impedance transformation and broadband balun. Then a four-arm sinuous antennas working at 0.4GHz to 2GHz is given, the measured results of VSWR and radiation pattern show that the feed form is reliable and...
In this paper, we present a wideband planar e-shape textile antenna and study its performance numerically and experimentally. The textile material and the radiation patch shape provide the antenna a wide working band (2.25ghz-2.75ghz). A digital human model is established to numerically analyze the affect of human body on antenna. Experiments are carried out to study the performance of antenna on...
A triple-band monopole antenna with a compact size of 28mm×33mm is presented and experimentally discussed for Wireless Local-Area Networks (WLAN) and World Interoperability for Microwave Access (WiMAX) applications. The proposed antenna fed by a 50-Ω microstrip feed line comprises a T-shaped monopole radiating patch and a wide-slot ground plane. With the introduction of a wide slot etched in the ground...
A compact dual-band planar monopole antenna for 2.4/5GHz WLAN application is presented. The two resonant modes of the proposed antenna are associate with four slots which contribute to the upper resonant frequency and can reduce the size of the lower resonant length. The parametric study is performed to understand the characteristics of the proposed antenna. Experimental results show that the designed...
