Measuring 2.4 GHz Helix Antennas

چکیده
In 1946, John D. Kraus invented the helical-beam antenna (or axialmode helix).1 Commencing with Kraus’s correct hypothesis that travelling-wave structures then used in electromagnetic devices would make efficient antennas, the helix antenna has proven to be the radiator of choice for many radio astronomy and spacescience applications. The helical antenna has been carried to the Moon and Mars, and the

A Compact MIMO Antenna Design for 2.4 GHz ISM Band Frequency Applications
In this paper, compact antenna has been designed that can be implemented in a 2X2 Multiple-Input MultipleOutput (MIMO) system. A microstrip patch antenna fed by a microstrip line is designed for a frequency of 2.4 GHz used for industrial, scientific and medical (ISM) band applications. Polarization diversity of the two antennas is used to construct independent and uncorrelated signals on each a...

In this paper, compact antenna has been designed and implemented in a 2X2 Multiple-Input Multiple-Output (MIMO) system. The antennas are compact double-sided printed microstrip patch antennas and fed by a microstrip line designed for a frequency of 2.4 GHz used for industrial, scientific and medical (ISM) band applications. Polarization diversity of the two antennas is used to construct indepen...
متن کاملReview of Amateur-Built 2.4-GHz Wireless-LAN Directional Wire Antennas
This paper is a review of amateur-built high-directivity wire antennas, for wireless local area network (WLAN), operating at 2.4-GHz frequency range. Those antennas can be deployed for range extension and interference reduction, for example. Covered in this review are a biquad antenna with reflector, Yagi-Uda antenna, and helical antenna. The distinctive feature of these antennas is their ease ...

متن کاملPolarisation-Diverse MIMO System Performance for Mobile Phones Wlan Application
A triple dual-band inverted F antenna system is presented, intended for MIMO applications in mobile handsets accessing high-speed wireless local area networks (IEEE 802.11a/b/g/n standards). A comprehensive study was carried out in order to understand the enhancement of channel capacity and the effect of polarisation diversity. Means of achieving minimum coupling between the three antennas were...
