adaptive antennaPulse Electronics introduced 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 fast data transmission rates in mobile phones, smart phones, and tablet devices. According to the company, it 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. 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 3-5 decibels (dB) for single hand browse modes, while on-ground top mounted antennas enrich performance by 1.5-2.5 dB for talk mode, according to the company. The antenna communicates with the host engine using an MIPI/SPI type digital control. Very little interaction is required with the engine.
