A Novel Compact Monopole Antenna for C Band/Wi-Fi/IEEE 802.16 Systems
A novel compact rectangular monopole antenna with four rectangular slots in radiating patch is proposed for Wireless Fidelity (Wi-Fi) applications and in IEEE 802.16 systems. The proposed antenna has simple and compact structure, and the prototype of the proposed antenna has been fabricated and measured. The designed antenna, fed by a 50O microstrip transmission line, is only 10mm in length and 3.2mm in width. The dual band antenna has operating bands with 10-dB return - loss bandwidth of about (46%) 3.1 GHz centered at 6.639 GHz and (24%) 2.9GHz centered at 12.02 GHz. Also, good radiation performance and antenna gain over the two frequency ranges have been obtained.
