1044 SMD LP patch antenna

Yageo Corp. has announced the 1044 SMD LP patch antenna that is half the size of traditional chip computers, yet achieves 80 percent better efficiency for GPS applications in personal navigation devices (PNDs), smart phones and notebooks.

Measuring 10mm x 4mm x 4mm, the 1044 SMD LP patch antenna supports bandwidth of 15MHz around central frequency of 1575MHz and working temperatures from -25C to 85C. Featuring both superior performance of pin antenna and miniaturization of patch antenna, Yageo's 1044 SMD LP patch antenna is designed with 20 percent to 30 percent enhanced performance versus conventional chip antenna, empowering smart phones to integrate personal navigation and positioning functions.

Vincent Hu, president of Yageo's global sales business group said that they are pleased to get a head start on offering an antenna "using high-k dielectric material in its proprietary multi-layered ceramic manufacturing process." He explained that "Driven by increasing demand for portable devices with versatile functions, smart phones constrained by limited space are often compelled to trade performance for size or vice versa in the selection of antenna." The new antenna, he claims makes this choice unnecessary.

Global GPS shipments are forecast to grow at an annual compound rate of 26.2 percent to 560 million units in 2012 from 175 million in 2007. The steady growth will be underpinned by increasingly dynamic GPS applications which extend beyond PNDs to smart phones, PNDs and notebook computers, according to Swedish Berg Insight.
