Název v původním jazyce
Daulband Quarter Wavelength Plannar Antenna for Signal Detection in GSM 900/DCS 1800 Bands
Popis výsledku v původním jazyce
Properties of dual band quarter wavelength planar antenna for signal detection in GSM900/DCS1800 band are presented. The antenna consist of two quarter wavelength planar antennas with air dielectric with one point feed. Reflection coefficient in uplink subbands (from mobile station MS to base station BS) of both bands at presented antennas versions is not as good as is required for trasmitting antennas but in case of antennas for signal detectionpurposes is quite goog enough. Directional characteristicshas been measured too.
