In this study, a quad-band folded slot antenna with a monopole feed line embedded in a conductive housing structure (the LCD bracket of a mobile phone) is proposed. The performance of the proposed antenna is evaluated through simulation and measureme

This paper presents a new wire-bond free technique for suppressing slot-line mode excitation in coplanar waveguides (CPWs) bends. The suppression of slot-line mode is obtained by applying a slow wave structure to the shorter slot of the right-angle b

In this paper, we present an inexpensive design technique that suppresses slot-line mode excitation in CPW right-angle bends without air-bridges. This design technique suppresses the slot-line mode by equalizing the travel time of electromagnetic wav
