AN91445 - Antenna Design and RF Layout Guidelines
AN91445 explains antenna design in simple terms and recommends two Cypress-tested PCB antennas that can be implemented at a very low cost for use with the Bluetooth Low Energy (BLE) solutions that are part of Cypress’s PRoC™ and PSoC® families. The PRoC BLE and PSoC 4 BLE 2.4-GHz radio must be carefully matched to its antenna for optimum performance. It concludes by showing how to tune the antenna in the final product.
An antenna is a critical component in a wireless system that transmits and receives electromagnetic radiation in free space. The wireless range that an end-customer gets out of an RF product with a current-limited power source such as a coin-cell battery depends greatly on the antenna design, the enclosure, and a good PCB layout.
