In this article, the design of a new bandpass filter, based on a modified circular mushroom metamaterial structure, is proposed. Half circular mushroom cells are used as the zero-order resonators (ZOR), and an intermediate gap is used to capacitively c...
Wireless communication gadget users nowadays tend to pursue more convenience, such as multi-functions and higher mobility. The former results in a multi-band service oriented device; the latter drives the development of reduced size equipment. Thus, the roles and expectations of RF components are becoming more challenging. In particular, quality...
