PRODUCT BRIEF: 802.11a Part No. 1001430, 1001388 PresttaTM Standard 802.11a 5GHz KEY BENEFITS DESIGN ADVANTAGES Ethertronics’ Prestta series of Isolated Magnetic Dipole™ (IMD) embedded antennas address the challenges facing today’s product designers. IMD’s high performance and isolation characteristics offer better connectivity and minimal interference. Prestta antennas can be used in a variety of applications in-cluding:  Handsets  Video Bridges  Gateway, Access Points  Tablets  M2M  Automatic Meter Reading  Healthcare  Point of Sale TECHNOLOGY ADVANTAGES Stays in Tune IMD antenna technology provides superior RF field containment, resulting in less interaction with surrounding components. Ethertronics IMD antennas resist de-tuning; providing a robust radio link regardless of the usage position. Prestta antennas use patented IMD technology in a stamped metal configuration to provide high performance. IMD antennas requires a smaller design keep-out area, carry lower program development risk which yields a quicker time-to-market, without sacrificing RF performance. Reduced Costs and Time-to-Market  Standard antenna eliminates design fees and cycle time associated with a custom solution; getting products to market faster. Greater Flexibility with Unique Form Factors  Ethertronics’ IMD technology helps you deliver more advanced ergonomic designs without adverse impact on product performance.  SMD mountable design enables faster and lower cost manufacturing. RoHS Compliant  Ethertronics’ antennas are fully compliant with the European RoHS Directive 2011/65/EU. END USER ADVANTAGES Unique Form Factors Support Advanced Industrial Designs  Smaller, more efficient IMD embedded antennas break through restrictive design rules and provide new freedom in component placement. Superior Range  Better antenna function means longer range and greater sensitivity to critically precise signals— delivering greater customer satisfaction while building brand loyalty. SERVICE AND SUPPORT Extensive RF Experience  Our Prestta antennas are supported by documentation, and when needed, by the expertise of RF engineers who have integrated hundreds of antenna designs into wireless devices. Global Operations & Design Support  Ethertronics’ global operations supports an integrated network of design centers that can take projects from concept to production.

The land patterns are composed of a 50 ohm line connected to each antenna feed point (1 feed, 1 ground). The feed line can either be connected to a 50 ohm transmission line or a 50 ohm coaxial cable. Ground clearance around and under the antenna, as shown in the PCB layout below, is recommended in order TOP Metallic Layer Layout BOTTOM Metallic Layer Layout © 2015 Ethertronics.
