A sensitivity analysis performed in order to improve the bandwidth, while the center frequency is kept constant...A novel slot-coupled barbel antenna is designed and analyzed.

Abstract|A novel dual-broadband circularly polarized folded slot antenna with single-feed is presented. The proposed antenna consists of two folded annular slots. By adjusting the asymmetric widths of the two slots, circularly polarized radiation can be achieved in two difierent bands.

Abstract This paper proposes a new and simple design for a broadband planar antenna with bi- and uni-directional radiation for WLAN applications. The broadband operation is realized by loading a patch into a circular aperture slot, which is fed by a micostrip line on... TANGENTIALLY FED BROADBAND ANNULAR SLOT …

Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.

A simple structure concentric annular-ring slot dual-band circularly polarized (CP) microstrip antenna operating at ISM band (2.45 GHz) and 5G band (3.5 GHz) is proposed in this paper. The antenna achieves dual-band operation by digging two concentric A Broadband Multi-layer Dual-polarization Slot Antenna Based ...
