Hinged, polarization diverse WLAN antenna

Abstract

To fully realize the system potential of wireless local area networks(WAN), polarization diverse antennas must be employed to minimize fading and optimize performance in dynamic, complex electromagnetic environments. An antenna solution that is integral to a W A N PCMCTA card has been developed, demonstrated and the results presented here.

A comparative study of diversity gain and spatial coverage: Fixed versus reconfigurable antennas for portable devices

“…(2) and (3) with a reliability rate of 99 or 1% outage for a dual branch system. For each branch receiver, ⌫ represents the mean SNR and the variable ␥ s represents a specified value or threshold SNR that determines the reliability in the resulting diversity gain.…”

“…The authors in Ref. 2 integrated a single rotating diversity antenna onto a wireless local are network (WLAN) card and characterized its performance via test and measurement. Similarly, the approach in Ref.…”

“…To find the optimal design of an optical communication system with specific requirement, accurate and rapid analyses and simulation of semiconductor laser performance, such as small-signal modulation bandwidth, dynamic impedance, intensity, and frequency noise levels, large-signal nonlinear distortion, etc., are required [1][2][3][4]. Many sophisticated computer programs [5][6], analytical solutions [7,8], numerical integration simulation model [9], and equivalent circuit models [10 -15] have been established and can accurately predict important characteristics of semiconductor lasers.…”
