The mobile device market desires smarter antenna solutions to enrich end user experience and decrease operator network investments. In addition, the expanding spectrum of operating frequencies and faster data transmission rates truly pose a challenge to the design of antennas.
Due to the reliable downlink with the Pulse smart antenna concept, operators derive cost savings in the investments that they make in the network. At the same time, with the correct antenna, mobile device users experience fewer dropped calls, higher data rates, reduced power consumption, increased talk time, an improved link budget in all conditions of use and savings in money and time due to more reliable downlinks/uplinks.
The Pulse adaptive antenna solution reduces the hand-effect in antennas, so the mobile device performance is not severely affected in the event that the antenna is covered by the user's hand. The smart antenna solution can be used in any mobile device and is not dependant on the technology used– it is applicable with GSM, CDMA, HSPA+, LTE, LTE-A.
The adaptivity of the antenna is based on a dynamic antenna matching (DAM) circuit with a switchable antenna design that enables the antenna to change its resonant frequency and input impedance to compensate effectively for the hand effect. Both on-ground or off-ground configurations are available.
The adaptivity in bottom mounted ground clearance antennas improves the performance by 3-5 decibels (dB) for single hand browse modes, while on-ground top mounted antennas enrich the performance by 1.5-2.5 dB for the talk mode.
The antenna communicates with the host engine using analogue control lines / SPI type digital control. The only information required from the engine concerns the operating band (which is typically available for the front end).
The smart antennas of Pulse are a continuation of its switchable antenna family that was first introduced in 2004. They are applicable for existing architectures and can be optimised for different antenna concepts and form factors. Standard manufacturing technologies, such as LDS or flex, can be used. Several customisation options for the mechanics and module structures are available.
