It has been demonstrated that circular ring antenna can satisfy the critical requirements for UWB antennas [4]. William and Nakkeeran in [5] presented the design and analysis of a new coplanar waveguide (CPW) fed ultra-wideband (UWB) slot … Microsoft Word - str_0195-0202.doc Abstract. A dual band circularly polarized single-feed applications in mobile and wireless devices due to their microstrip antenna for wireless communication systems is lightweight, low profile, planar configuration and com- proposed here … Radioengineering - April 2015, Volume 24, Number 1 [DOI: 10… This paper presents a new design of dual-band bandpass filters using coupled stepped-impedance resonators for wireless systems. dual band thermal: Topics by WorldWideScience.org
A Compact Dual-Band Bow-Tie Slot Antenna for 900-MHz and ... - NDSU
CPW-fed ultra-wideband slot antenna with broadband dual ... To better explain the antenna design, Fig. 2 shows four evolution stages of the antenna. Initially, a square slot antenna with two CPW-fed ports are depicted as shown in Ant.1 of Fig. 2. It provides two operating bands at around 3.8 and 15.6 GHz with narrow impedance matching and only has linearly polarized feature. Design of a Dual-Band Microstrip Patch Antenna for GPS ... The dual frequency and wide-band operation of a trapezoidal patch with V-shaped slot have been studies and simulated. The proposed antenna is compact, occupies small volume and has simple structure compared to other antenna design. The antenna offer a 2:1 VSWR bandwidth of 4% from frequency range
