Abstract: High-gain omnidirectional antennas are widely used in outdoor emergency communication systems. This paper presents a multi-section omnidirectional high-gain base station antenna based on ...

The antenna operates in the 5150 to 5875 MHz band with 5 dBi gain and linear vertical polarization (VPOL). VPOL increases the range of the antenna over hilly terrain and also minimizes the reception ...

The antenna operates in the 2400 to 2500 MHz band with a 9 dBi gain and horizontal polarization (HPOL). HPOL increases the range of the antenna over flat surfaces and minimizes vertically polarized ...

Omnidirectional antenna handles AMPS, GSM, PCS, DCS, UMTS, and Wi-Fi technologies Presented as the smallest device of its kind, the 179 x 80 x 1.7-mm UltraSphere CAF 94895 wireless in-building antenna ...
