In this paper, Design of a reconfiguration frequency full metal case antenna with portable wireless terminal unit is presented in the Fig. 1. The prototype antenna in fabricated is used a copper sheet of 0.6mm thickness while occupies a volume of 13mm × 70mm × 0.6 mm, and suitable to be built-in housing of a mobile phone. A FR4 substrate with a thickness of 0.8 mm, relative permittivity of 4.4, and...
As the demand for wireless products increases, low cost and high integration have become the major issues in RF circuit design. It is critical for RF system designers to offer multistandard operation while at the same maintaining competitive hardware costs. For example, global system for mobile communications (GSM) and wideband code division multiple access (WCDMA) mobile communications standards...
A high performance wire monopole antenna fabricated using two meander wires as radiator is presented. A prototype of the proposed monopole antenna with a compact area size of 24mm × 10mm is implemented, and the multi-band WLAN antenna shows a wide operating bandwidth of about 637MHz and 1000MHz for low band and high band, bandwidth, making it easy to cover the IEEE 802.11a, IEEE 802.11b, IEEE 802...
Wireless mesh networks (WMNs) have experienced an enormous growth over the past few years. The performance of WMNs depends on the joint effect of both routing algorithms and rate adaptive algorithms. The performance of various routing algorithms has been studied extensively in the literature. However, little work has been done to evaluate the cross-layer impact of rate adaptive algorithms in WMN environments...
In recent years, wireless communications have progressed very rapidly. Wide-band antenna and multi-band antenna designs have become very important for wireless communications. Several promising monopole antennas for WLAN and WiMax applications have been reported recently. According to the WiMax protocol, there is three bands have been allocated for WiMax application: the lower band is 2.5-2.69 GHz,...
A high performance monopole antenna fabricated using a folded wire line and a metal patch as radiator is presented. A prototype of the proposed monopole antenna with a compact area size of 20 mmx10 mm is implemented, and the multi-band WLAN antenna shows a wide operating bandwidth of about 200 MHz and 1000 MHz for low band and high band, bandwidth, making it easy to cover the IEEE 802.11a, IEEE 802...
