A design of high dielectric constant hybrid planar F-antenna for S, C, X and Ku band applications

In present days patch antennas became more important in microwave communications because of their low cost, low weight and easy of fabrication but one disadvantage is narrow bandwidth. Similarly PIFA antennas became more important in mobile communications due to there are small in size and the foldable PIFA antennas are also available in market. Here an antenna with high dielectric constant i.e 10.2(RO 3010) being used to design of proposed antenna from the concepts of rectangular patch antenna and one shorting pin used which is from concept of F-antenna. This antenna has resonant frequencies at 2.7GHz, 6.93GHz, 9.85GHz, 12.1GHz which can be used in many communication applications and corresponding far field patterns are also calculated using CST Microwave studio.
