BASICS A Flexible PCB antenna with cable is a very flexible, low profile, highly reliable and economical solution widely used in the wireless industry. Usually consisting of polyimide flexible PCB (polyimide), a trace is printed on the substrate to get the desired antenna topology. Various antenna types such as monopoles, dipoles and printed F antennas can be made. This design application note is intended to help the antenna integrator understand the relevant parameters affecting the antenna performance. Taoglas recommends that the integrator strictly follow the guidelines in this application note, upon your device prototype completion Taoglas can provide further optimization by custom tuning and testing service of the antenna in your device. (see Note 15 on Page 6 for further info on Tuning) 2. APPLICATIONS A Flexible PCB antenna with cable is suitable for mobile applications or areas where internal antennas are required or where not much space or volume is available. It is ideally affixed to the plastic housing of a device directly by double- sided adhesive. Taoglas Flexible PCB antennas come in single-band or multi- band solutions. Starting from 450MHz up to 6 GHz. 3. SIZE The larger the antenna surface area (or volume), in general the higher the performance in terms of gain and radiation characteristics.
