The lack of spectrum harmonization represents a key challenge for the emerging LTE ecosystem, potentially preventing vendors from delivering globally compatible LTE products such as devices and chipsets. Spectrum fragmentation has the potential to hinder global LTE roaming if device manufacturers are required to include support for many disparate frequencies in their devices. AMANT Antennas is providing the market with a novel antenna technology to solve the problem of urgent need for universal LTE devices. The new technology can cover all the possible LTE spectrum bands (40 bands) using only two antennas with bandwidths of 73% and 85% respectively without using any matching or tuning circuits with very high efficiencies. Thus, it saves the battery life time of the power hungry smart devices. The antenna design is made of flexible material which can be bended and/or wrapped. Moreover, it can be mounted anywhere inside or outside any handset because the antenna does not use a part of the handset as an extended ground plane as usually happens with internal antennas.

The low band antenna can cover:

·LTE spectrum starting from 698 MHz up to 1.51 GHz which includes LTE band numbers 5, 6, 8, 11, 12, 13, 14, 17, 18, 19, 20, 21, 26, 27, 28, 29, 44.

·WiMax (700MHz)

·CDMA/TDMA/GSM800 (824-894 MHz)

·E-GSM900 (880-960 MHz)

·low L band GPS (1.2GHz)

·L-band DVB-H (1452–1492MHz)

The high band antenna can cover:

·LTE spectrum starting from 1.52 GHz to 3.8 GHz which includes LTE band numbers 1, 2, 3, 4, 7, 9, 10, 22, 23, 24, 25, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42 and 43.

·GPS (1575MHz)

·GSM1800 (1710–1880MHz)

·PCS1900 (1859–1990MHz)

·UMTS (1900–2170MHz)

·Bluetooth/WiFi (2.4GHz)

·Handheld satellite phones (1.6 GHz downlink, 2.5 GHz uplink)

·WiMax (2.3-2.5 GHz)  

·IMT-2000 WiMax(2.5-2.69 GHz)

These small size antennas can be used as feed antennas for AMANT’s dual parabolic base station antenna.
