“…Therefore, electromagnetic energy in the very narrow slotline is mostly reflected into the feedline and hardly radiated. To improve the radiation performance from the very narrow slotline, some research results have been introduced [1]- [3]. However, these approaches have not provided simple and practical solutions.…”

In this letter, a simple design to improve an antenna radiation performance by adding a matching network consisting of short-ended double spur-line is proposed. By inserting a short-ended double spur-line in the slotline and connecting it with a ground plane, a parallel resonance with a bandpass characteristic occurs, and the characteristic impedance of the very narrow slotline is close to the impedance of free space. To verify this characteristic, an equivalent circuit model is presented to offer a detailed explanation, and the comparisons between the simulated and measured results are demonstrated.

This paper presents the microstrip antenna with triangular tuning stub which designed and simulated by using IE3D program. This antenna is designed for 50 Ohms impedance microstrip line for dual band frequency, 2.297-2.952 GHz and 5.138-6.051 GHz which supports WLAN communications coverage IEEE 802.11b/g (2.4-2.4835 GHz), IEEE 802.16a (5.15-5.35 GHz) and IEEE 802.16d (5.7-5.9 GHz). The bandwidth at lower resonance frequency of this antenna is 0.655 GHz, while upper resonance frequency is 0.913 GHz. The simulation results show that the lower and upper resonance frequencies are agreed with the measurement results.

“…However, most of the designs were meant for narrow band operation and the studies focussed on the first resonance of the slot. Some of the rectangular slot antennas designed for wider bandwidth are listed in references [2][3][4][5][6]. In [2], a dual band operation is achieved by the combination of a narrow slot and slot loop.…”

Abstract-A rectangular slot antenna for UWB applications is proposed in this paper. The slot is designed in stepped configuration and is excited by an L-shaped microstrip line flared at the end. The measured impedance bandwidth (−10 dB) from 3 GHz to 27 GHz is achieved. The radiation patterns are bidirectional in the E plane and omnidirectional in the H plane with the measured peak gain around 5 dBi throughout the band. The experimental results are in good agreement with the simulated results. A detail parametric study is done for the flare angle and the flare width to axis ratio and their effect on the impedance bandwidth and the reflection coefficient is described.
