Comparative analysis of CPW fed antenna with different substrate material with varying thickness

A Contemporary Review of High Voltage Partial Discharge Detection and Recognition Techniques

“…Fundamentally, the electrical as well as physical factors are crucial in designing a PD antenna centred on a microstrip patch antenna. The electrical parameters related to material or substrates to build up the main antenna structure; among the popular material to be selected as substrates are FR-4 epoxy, Rogers RT Duroid 5880 (TM) Polytetrafluoroethylene (PTFE) composites, Taconic TLC-27 Polytetrafluoroethylene (PTFE), Roger RO4003, GML1000, and Bakelite [52][53][54][55]. Whereas, the physical parameters are the ground plane, feed point, and top patch normally improved to accomplish designated resonant frequency with a good reflection coefficient of minimum of -10 dB and wider frequency bandwidth of more than 100 MHz [44,[56][57][58].…”
