Abstract
In this paper, two new types of fractal monopole antennas named Penta-Gasket-Khoch (PGK) and Complementary-Penta-Gasket-Khoch (CPGK) are introduced. My designs have achieved a good input impedance match throughout the pass band (2–20 GHz), but some occasional irregular small mismatch exists. These antennas are suitable for applications in picocell environments for the operating bands of ICMS, UMTS, Bluetooth, WLAN and HIPERLAN systems. Further optimization and some manufacturing aspects have been considered.
