Compact MIMO Antenna Array Design for Wireless Applicationss spread over a very wide frequency band, known as ultrawideband; secondly, MIMO (multiple-input multiple-output) transmission. Methods of achieving MIMO through spatial diversity require array antenna elements to be separated by significant fractions of a wavelength, giving a relatively bulky struc

Compact Wideband Balanced Antenna Structure for 3G Mobile Handsetss have been widely used. Such types of designs usually offer wide impedance bandwidth and compact design; however, the characteristics of the antenna property vary a lot when the phone is held by the user in talk position, causing performance degradation. On the contrary, balanced type of antennas f

Coplanar-Fed Miniaturized Folded Loop Balanced Antenna for WLAN Applications Within this design process, the need of the balanced feed network was eliminated. This is realized by carefully and systematically calculating and studying the influences of the key antenna modified parameters. This effective analysis was done with the aid of two EM simulator tools in order to ensu
