In this paper, a modified slot aperture feed is presented. This new feed is applied to a cubic-shaped Dielectric Resonator as a result it resonates antenna in higher order TEσ13 modes at 5.59 GHz to achieve enhanced directivity (11.6dBi). This new feed is engineered by replacing the rectangular stub of conventional slot aperture feed with a circular metallic strip of radius 3mm. Which enhances the...
In this paper, a novel feed is introduced which resonates antenna with high Gain and a better bandwidth. This modified slot aperture feed is applied to a Rectangular shaped dielectric resonator antenna (DRA) which resonates antenna with high Gain and Bandwidth covering the 3.6 GHz WIFI band (3.6575 to 3.6900GHz). The CST simulated results show that the antenna has the broad bandwidth of 1459MHz i...
A simple cubic shaped dielectric resonator antenna (DRA) resonating at 2.45GHz with 7.3dB Gain and 534MHz Bandwidth is presented in this paper for WLAN applications. In this design, a new concept of enhancing antenna Gain by using a small parasitic metal strip, coated on the cubic DR surface near to ground plane for steering the electromagnetic beam in opposite direction is introduced. The antenna...
This paper presents a tri-band dual-polarized cylindrical dielectric resonator antenna (DRA). To obtain dual linear polarization, the probe- and slot-fed excitation methods are used for Ports 1 and 2 of the antenna, respectively. The antenna makes use of two fundamental modes and three higher-order modes of cylindrical dielectric resonator to achieve tri-band. Also, the antenna has high input isolation...
A compact ultra-wideband (UWB) antenna with reconfigurable notch function is presented. The proposed antenna, with a compact size of 25×29 mm2, can be able to switch among eight operative modes,including a UWB mode, three single band notched modes, three dual band notched modes, and a triple band notched modes. Three different types of slots are introduced to generate three notched bands with central...
A very compact ultrawideband (UWB) multiple-input multiple-output (MIMO) antenna with high isolation is presented in this letter. The proposed antenna, consisting of two UWB slot antennas, has a very compact size of , which is smaller than most of UWB antennas only with single antenna element. A T-shaped slot is etched on the ground to improve the impedance matching characteristic...
