Abstract
A directly modulating antenna incorporating a reconfigurable Frequency Selective Surface (FSS) for arbitrary phase modulation is designed and simulated. A 4-layer FSS is used to minimise constellation distortion, with only 1.5dB variation in transmitted magnitude for 360° phase change. Low loss substrates and Barium Strontium Titante (BST) variable capacitors are simulated to reduce the antenna loss to 1.3dB in the filter pass band and achieve an average total efficiency of 65% when producing an 8-PSK constellation.
