Broadband Dielectric Loaded Trapezoidal Planar Antenna

摘要

This paper presents an optimised design of a broadband dielectric loaded planar monopole developed by Antenova Ltd. UK. With knowledge of its operating principle, the design is optimised to achieve a smaller dielectric size and an even wider impedance bandwidth. The bandwidth of the optimized antenna is up to 63%, covering four frequency bands, DCS 1800, PCS 1900, WCDMA 2100 and IEEE802.11 2400, using a smaller dielectric (ceramic) pellet, which is only 70% of the original one.
