APPLICATIONS Other patents pending. Mobile UHF TV receivers including DVB-T, DVB-H, ISDB-T, CMMB, ATSC, and MediaFLO devices DESCRIPTION The VJ 6040 multi-layer ceramic chip antenna is a small ANTENNE PERFORMANCE form-factor, high-performance, chip-antenna designed for TV reception in mobile devices in the UHF band. It allows Peak Gain mobile TV device manufacturers to design high quality The antenna radiation characteristics are influenced by products that do not bear the penalty of a large external several factors including ground plane dimensions and antenna. Utilizing Vishay s unique materials and impedance matching network. manufacturing technologies, this product complies with the The antenna parameters presented hereafter were MBRAI standard while maintaining a small outline. measured according to the configuration suggested by the Focusing on consumer applications, the antenna is VJ 6040 evaluation board, utilizing its four channel active designed to be assembled onto a PC board in the standard digital tuning circuit. The evaluation board ground plane is reflow process. 40 mm by 80 mm large. Target customers of the VJ 6040 are mobile phone makers, Fig. 1 shows peak gain over frequency throughout the UHF portable multimedia device makers, notebook OEMs and band, compared with the MBRAI requirements. ODMs, and accessory card OEMs and ODMs. The VJ 6040 is the first of a family of products developed by Vishay, a world leader in manufacturing of discrete and passive components. 0 -2 Simulated Measured -4 -6 Standard -8 -10 -12 450 500 550 600 650 700 750 800 850 900 Frequency (MHz) Fig. 1 - Peak Gain vs. Frequency Revision: 07-Mar-17 Document Number: 45157 1 For technical questions, contact: chipantenna vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
