A compact ultra-wideband microstrip-fed planar monopole antenna with dual band-notch characteristic is presented. Dual notched frequency bands are achieved by embedding an M-slot in the radiating patch and a W-slot in the ground beneath the feeding line. And the characteristics of the dual band-notched can be controlled by adjusting the length and position of the corresponding slot. Experimenta...

In this paper, Microstrip patch antenna fed through an aperture coupled 50Ω microstrip line is designed for dualband and tripleband applications by cutting U-slots in the patch. When a U-slot is cut in the patch, a notch is introduced within the matching band, results in dualband antenna. If another U-slot is cut in the same patch, antenna becomes a tripleband antenna. For better coupling apert...

In this paper, a printed hexagonal wide slot antenna, fed by a microstrip line with fork like tuning stub for bandwidth enhancement is proposed and experimentally investigated.

Initially, the antenna radiator is designed at quarter wavelength of 1.8 GHz. A ground slot is then introduced and loaded with two pair of PIN diode switches to create a new tunable magnetic resonato...

Compact shorted 1350 Sectoral microstrip antenna derived from 2700 Sectoral microstrip antenna is proposed. On thicker air substrate (h > 0. 1?0) it yields bandwidth of more than 350 MHz (35%). To increase the bandwidth, its rectangular slot cut variation is proposed. The slot reduces the resonance frequency of higher order TM1/4,1 mode of the shorted patch and along with fundamental TM1/4,0 mo...

In this paper, a coplanar waveguide (CPW)-fed dual-band slot antenna with circular polarization (CP) is presented. In order to achieve CP characteristic, an asymmetric slot and F-shaped end patch are introduced to a conventional rectangular slot antenna. Moreover, by cutting a T-shaped notch on the ground plane, the axial ratio (AR) bandwidth (ARBW) can be extended. The antenna shows left-hand ...

The main focus of this paper is to study and analyze how the performance of rectangular U slot antenna is affected by the parameters like Feed point position.

Experimentally, it has been revealed that variations in parameters such as the width and length of the U-slot, height and size of the patch, probe size and location as well as substra...

A simple, compact, slot loaded stacked wideband microstrip patch antenna is presented in this communication. The radiating element consists of a rectangular patch with a Tshaped slot and is fed by a 50 Ω microstrip line. The proposed antenna is simulated using IE3D software, 12.32 version of Zeland. The simulated results show that the antenna can exhibit wideband characteristics. The impedance ...

Abstract—A probe-fed, slotted rectangular patch antenna has been proposed. Bandwidth enhancement has been achieved by suitably cutting slots into the rectangular patch, and efficiently exciting the slot by short circuiting the conducting patch through the dielectric substrate beyond the edge of the slot. Proposed antenna is suitable for various ground based and airborne applications in C-Band. ...
