Summary:
A novel photonic band-gap(PBG) structure for compactness is investigated. A comparison has been carried out between the proposed designs and the normal mushroom-like PBG structure. Experimental results show that a compact PBG configurations exhibit more excellent performances by suppressing ripple in the pass-band and stop-band return loss(RL). In the normal mushroom design, the stop-band extends from 3.63GHz to 6.18GHz. When the multiple slots are incorporated, the frequency band-gap position decreases to 3.27GHz-5.45GHz and 2.95GHz-5.07GHz, respectively. The presented structure also provides an additional degree of freedom to adjust the band-gap position, which is applied to design a novel reconfigurable multi-band PBG structure. Our proposed PBG designs may be used in various microwave integrated circuit(MIC), RF devices with highly compact size.
