Abstract :
This paper presents a broadband CPW-fed loop slot antenna incorporated with a photonic bandgap (PBG) structure in the feeding network. An asymmetric PBG structure, utilized to eliminate unwanted higher order modes, has been implemented experimentally. The experimental results show that a good characteristic of the suppression of higher order modes is observed; furthermore, the impedance bandwidth of the proposed antenna can reach 1541 MHz, which is about 70% with respect to the central frequency of 2200 MHz.
