Broadband pattern diversity annular slot antenna

A compact asymmetric coplanar strip (ACS)-fed ultra-wideband (UWB) antenna for diversity applications is presented. The proposed antenna is composed of two circular radiating elements and orthogonal ACS-fed mechanisms to achieve diversity performance across the UWB from 2.66 to 11.08 GHz, and occupies a very compact size of 28.5 × 28.5 mm2. By introducing a rectangular stub diagonally between ... Dual-Port Dual-Wideband Annular Slot Antenna with Stable ... annular slot antenna proposed in [23] provides dual-band feature with two concentric slot-rings and stable radiation pattern in both bands, but the dimensions of the cavity were too large, hence resulting in a bulky structure unsuitable for array design. In this paper, a compact dual-feed dual-band slot antenna is described. It has been ...

Tangentially fed broadband annular slot antenna .. The perimeter of the annular slot is around λs with λs the guided wavelength in the slot at the resonant frequency.The annular slot antenna described has been designed on ROGERS substrate RO4003 (Er=3.38, Tanδ=0.0027, h=0.81mm), at a central frequency of 5.7 GHz using the IE3D software from. Broadband Annular Slot Antenna with polarization … The Annular Slot Antenna (ASA) presents appropriate characteristics for many applications such as Wireless Local Area Networks [1]. Its inherent symmetryThe conventional Annular Slot Antenna (Figure 1a) consists in an annular slot cut into a metallic layer and backed by a substrate. Dual-polarisation and dual-pattern planar antenna for … The novel annular-ring slot antenna has been designed to [6] BEHDAD N., SARABANDI K. : ‘Wideband double-element implement a pattern/polarisation receiving diversity scheme ring slot antenna’, IEE Electron.
