The performance of an antenna will impact the communication range of a RF system. Since range is often a critical factor when designing RF systems, it is important to be able to characterize the antenna with network analyzer.
A combines multiple antenna elements with a signalprocessing capability to optimize its radiation and/or reception pattern automatically in response to the signal environment.
In the last few years a large technological jump has taken place in the field of mobile communications due to the introduction of new mobile communication networks (GSM/PCN). The number of subscribers worldwide has risen to over 150 Million. The req
An antenna is a crucial element in the successful design of any radio system. This paper explores antenna characteristics and different types of antennas that OEMs should consider when selecting an antenna.
Antenna performance is fundamentally a function of size measured in wavelengths at the operating frequency. “Electrically small” antennas are those that are small compared to the wavelength, not necessarily small compared to the people who use them.
improved interstitial microwave antenna design was investigated in static phantom experiments at 915 MHz and different insertion depths. Compared with conventional interstitial antennas, the dipole microwave antenna presented in this paper shows hea

Abstract—In this paper, we present a performance analysis of a smart antenna system operating in a wide-band CDMA wireless- local-loop channel using a beam-forming module (BFM) that has been implemented on a digital signal processor (TMS320C6701) bo
