Planar Ultra-Wideband Antenna with Added GSM Frequency Bands

A planar antenna design for ultra-wideband (UWB) communication with two additional GSM bands is presented in this study. A beveled-shaped patch with a quarter-wavelength transformer is utilized to provide UWB response. Two capacitive-loaded resonators (CLRs) are utilized in conjunction with a partial ground plane to create resonance in the GSM frequency bands (900 and 1800 MHz). The designed antennas’ prototype is fabricated and measured, and it is noticed that both the results are well in agreement. Furthermore, the proposed antenna design produces good radiation characteristics for the bands of interests.
