Abstract

In this paper, the potential use of complementary split‐ring resonators (CSRRs) to design very compact waveguide filters, by etching a CSRR in the center of a metallic sheet, is demonstrated. This original layout reduces the dimensions of the well‐known resonant‐cavity waveguide filters coupled by irises. This has been made feasible due to the self‐resonance property of the CSRR. Thus, it is possible to design waveguide filters with lengths equal to the thickness of a metallic sheet. Consequently, this technique paves the way for the design of miniaturized waveguide filters, in contrast to conventional waveguide filters, based on bulk resonators. © 2005 Wiley Periodicals, Inc.

A novel, planar inverted-F antenna with a slotted T-shaped ground plane is proposed. It is shown that introducing a cross-shaped slot onto the T-shaped ground can greatly broaden the bandwidth without affecting the operating frequency. The measured bandwidth of the proposed antenna is from 1950 to 2
