A QUAD-ANTENNA SYSTEM OPERATING AT THE 2.4/5.2/5.8 GHZ WLAN BANDS FOR LAPTOP COMPUTERS

Developing integrated antenna subsystems for laptop computers

The design, development, testing, and integration methodology for antennas integrated into laptop computers is described. Two key parameters are proposed and discussed for laptop antenna design and evaluation: standing wave ratio (SWR) and average antenna gain. A novel averaging technique was developed and applied to these to yield a measurable, repeatable, and generalized metric. A prototype a...

A WIDEBAND PRINTED MONOPOLE ANTENNA FOR 2.4-GHz WLAN APPLICATIONS

A planar monopole antenna suitable for broadband wireless communication is designed and developed. With the use of a truncated ground plane, the proposed printed monopole antenna offers nearly 60% 2:1 VSWR bandwidth and good radiation characteristics for the frequencies across the operating band. A parametric study of the antenna is performed based on the optimized design, and a prototype of th...

Design, Analysis and Optimization of A Slotted Microstrip Patch Antenna Array at Frequency 5.25 GHz for WLAN-SDMA System

The design of array antenna is vital study for today’s Wireless communication system to achieve higher gain, highly directional beam and also to counteract the effect of fading while signal propagates through various corrupted environments. In this study, the design and analysis of a (2x2) microstrip patch antenna array is introduced. It is designed to function in the 5.25 GHz which corresponds...

Tri-band Compact Antenna Array for Mimo User Mobile Terminals at Gsm 1800 and Wlan Bands

Distributed Antenna System for Mitigating Shadowing Effect in 60 GHz WLAN

The 60GHz unlicensed frequency band has been adopted to support high data rate WLAN applications. The problem of this frequency band is that the wireless signal is vulnerable to the shadowing of objects. Especially in indoor scenarios, humans may frequently block the signal paths that cause disconnections of devices. This problem can be mitigated by using multiple antennas that can create rich ...
