A modified microstrip line fed compact UWB antenna for WiMAX ... In the first step, a conventional rectangular radiating patch is taken as radiator and fed with spanner shaped microstrip line. This antenna 1 gives a triple band notched UWB response (3.28–24 GHz). In the second step, an arch shaped slot is etched in the feed line and a stepped slot is cut in the bottom left corner of the patch. What is the difference between slot antenna and patch antenna ... Slot antennas are easier to make and modify, though patch antennas can be nearly as cheaply made using printed circuit board production lines. Slot antennas can send much more powerful signals. You can build a slot antenna into a structure and put it somewhere others may not know it is. The Pros and Cons of Slot Antennas A Large Bandwidth T-shaped Microstrip-fed Ground Plane Slot ... When the T-shaped feedline is used, the bandwidth is extended proportionately to the slot width and the radiation resistance has a low value. The characteristics of a printed slot antenna fed with a T-shaped microstrip line have been studied. A bandwidth wider than for the conventional feed has been obtained.

Sayeed Abstract|In this article, the parametric analysis of the slot-loaded microstrip line feed patch antenna is investigated using artiflcial neural network model.
A Hexagonal Shape Microstrip Slot Antenna for Wideband and Multiband Applications. Sujeet Kumar Yadav, Kirti Vyas, Sudarshan Kumar. Abstract- Here in this paper a compact microstrip antenna having wide-slots of hexagon shape is fed by microstrip-line for wideband and multi band operations is proposed and studied. The proposed antenna resonates ... Chapter 5 Impedance of Slot Antennas 5.1 Introduction present calculations for a slot fed by a microstrip line with a bolometer detector centered between the two slots. The feed line is electromagnetically coupled to the slot antennas so no direct connections to the ground plane are necessary which simplifies the fabrication of the feed network and antennas. We present calculations Study and Design of a Differentially Fed Tapered Slot ... such antenna array concepts, thereby facing one of the biggest Abstract—The results of a parametric study and design of an ultra-wideband dual-polarized array of differentially fed Tapered Slot Antenna elements are presented. We examine arrays of bunny-ear antennas and discuss the capabilities and limitations of differential antenna technology. HFSS - Design of Rectangular Patch Antenna using ...
The first design (Type-I) consists of a microstrip line on one side and an elliptical slot (ES) on the other side of the substrate. The second design (Type-II) consists ...
Aperture Coupled Microstrip Antenna Design and Analysis Michael Paul Civerolo A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software [1]. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation Microstrip‐fed cavity‐backed slot antennas - Li - 2002 ... Two types of cavity‐backed slot (CBS) antennas fed by a microstrip line and operating at 5.8 GHz are described in this letter. One is a broadband linearly polarized CBS antenna, which can provide 34% bandwidth for a 10‐dB return loss.
The printed microstrip-line-fed broadband rhombus slot antenna is investigated in this paper. With the use of the offset microstrip feed line and the corner-trun-cated protruded ground plane, the bandwidth enhancement and the slot size reduction for the proposed slot antenna can be obtained. The experimental results demonstrate that the ...
