Design of Microstrip Antenna for Wireless Local Area Network

Modern wireless and mobile communication systems requires antenna which should have light weight, low profile, low cost, and easy to be integrated with RF devices. This demand is completed by microstrip antennas. This paper presents rectangular microstrip patch antenna for WLAN applications designed using IE3D software. The microstrip antenna is designed with dielectric substrate as Rogers RT/d...

Smart-antenna operation for indoor wireless local-area networks using OFDM

This paper reports link-level Monte Carlo simulations for a system that is compatible with the physical layer of the 5-GHz IEEE 802.11a wireless-local-area network and utilizes an adaptive antenna array at the access point for single-user smart-antenna operation, as well as for space-division multiple access (SDMA). For the spatial indoor radio propagation channel, complex impulse-response reco...

A Multiband Multiple-input Multiple-output Antenna System for Long Term Evolution and Wireless Local Area Networks Handsets

A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...
