Compact CPW-Fed Multiple Broadband Planar Monopole Antenna

This paper presents a kind of CPW-fed Pentagon-type multi-band planar monopole antenna. It provides an integrated wideband operating frequency band coverage from 900MHz of GSM to 10.6GHz UWB applications. This is the desirable antenna characteristic that is suitable for modern integrated mobile broadband wireless radio access applications. The proposed antenna was fabricated in practice with the FR4 print circuit board having 1.6 mm substrate thickness and dielectric constant of 4.4, tangent loss constant of 0.02. The measurement results show the success of the proposed planar monopole antenna. The detailed antenna design parameters are given in this paper. The characteristics of this type antenna, wide in bandwidth, low in profile, light in weight and small in size and single layer fabrication can be beneficial in the future integration with other microwave circuit of wireless systems.
