Pulse Intros Smart Mobile Antenna
"Smart" mobile antenna helps designers.
San Diego, CA — Pulse Electronics Corporation is introducing its new adaptive antenna concept. This smart antenna can be adapted for integration into devices that use an expanding spectrum of operating frequencies and enables faster data transmission rates in mobile phones, smart phones, and tablet devices.
The technology eliminates the "hand effect" in long term evolution (LTE) multiple-input and multiple-output (MIMO) antenna solutions so phone performance and function are not affected if the antenna is covered by the user's hand. Operators derive cost savings in the investments they make in the network because of the reliable downlink.
The adaptivity of the antenna is based on a dynamic antenna matching (DAM) circuit with switchable antenna design that enables the antenna to change resonant frequency and input impedance to compensate effectively for the finger/hand effect, offering flexibility in positioning for the designer of the device. Either on-ground or off-ground configurations are available.
Adaptivity in bottom mounted ground clearance antennas improve performance 3-5dB for single hand browse modes, while on-ground top mounted antennas enrich performance by 1.5-2.5dB for talk mode.The antenna communicates with the host engine using an MIPI/SPI type digital control. Very little interaction is required with the engine.
The company's smart antennas are a continuation of its switchable antenna family that was first introduced in 2004. They are applicable for existing architectures and manufacturing technologies such as laser direct structuring (LDS) and flex and are easily optimized for different antenna concepts. Several customization options for the mechanics and module structures are available. The antennas are customized and packaged in trays, and demonstrators are available.
