A novel reconfigurable PCB antenna for 2.4 GHz wireless consumer product is proposed in this paper. The emphasis is to reduce the design and development time, and hence Time to Market. The proposed antenna and mechanical reconfiguration methodology have been verified from measurements by fabricating the antenna on various PCB size. FR4 PCB is chosen since it is widely used in industry for most consumer...
A novel compact four bands antenna with coplanar waveguide feed is proposed for satisfying GSM, WLAN and WIMAX. Based on the triangle planar patch element, two different slots were embedded. The simulation of the antenna is performed by using software Ansoft HFSS and the results present that the number of multiband, the central of frequency and bandwidth can be controlled by the dimensions of the...
Time-domain broad-band antenna usually used for transmitting and receiving electromagnetic pulse signal. A miniaturization plate monopole broad-band ring antenna fed by coplane waveguide was proposed, through researching on the basic parameters that as sign of broad-band antenna's timedomain characteristic and analyzing the characteristic of microwave pulse time-domain test antenna, and this antenna...
A novel near-field measurement method for predicting far-field monostatic RCS of targets is studied. With the two-dimensional problem as an example, the theory and algorithm of near-field to far-field transformation for this measurement method are derived. With the two-dimensional perfect conductor plate as the target under test, the computer simulation of this measurement method is performed. The...
This paper presents the theory, design, fabrication and measurements of high gain compact size horn lens antenna for next generation gigabit point-to-point wireless communications at E-band (71–76GHz and 81–86GHz). A wide flare angle pyramidal horn antenna is integrated with fully flat inhomogeneous low loss (<2dB) dielectric lens that is covering the horn antenna aperture without additional impedance...
Operating as the sensor of the body centric wireless network, the wearable flexible antenna has become an important component of the fourth generation mobile communication (4G). Based on the design requirements of the wearable flexible antenna, a antenna with low profile, light weight, and easy processing technique is presented. The proposed antenna was designed on the thin microwave substrate with...
