Bandwidth Enhancement of Corporate Fed Bowtie Antenna Array operating in L Band by Changing the Substrate Material and Ground Plane Length

Abstract

This paper presents analysis of Multiband Corporate fed Bowtie Antenna Array having tuned in L Band. Bandwidth performance is analyzed for different substrate materials and effect of ground plane is presented. Simulation result shows that proposed antenna using Roggers RT/Duroid matarial is tuned at frequencies 1.05 GHz, 1.63GHz, 2.25GHz and 2.92GHz and provides 40.95%, 18.40%, 14.66% and 17.97% bandwidth respectively. Proposed antenna can be used for applications such as WCDMA, Mobile Satellite services, point to point, TV pickup and subscriber radio system (SRS). The antenna is simulated on HFSS virtual tool.

An Improved Design of Slotted Microstrip Patch Antenna for X Band and Ku band Applications

“…It leads to good radiation efficiency and acceptable dimension [13]. As shown in figure 3, the normal components of electric field has equal amplitude but opposite phase at the edges, so cancel out each other in perpendicular direction [14].…”

A Planar Semi-Circled Horn-Like Bow-Tie Antenna Array for Amateur Radio Applications

“…The Bow-Tie antenna is one of the many varieties of micro strip patch antennas, and it is considered a good option for a number of wireless applications, including amateur radio applications. The fact that these applications have a resonant at several frequencies in the vicinity of 2.4GHz, 3.6GHz, 3.9GHz, and 4.9GHz makes them feasible [4,8,11,17,23].…”

Analysis of Triple Band Rectangular Patch Antenna Loaded With Pairs of L Shaped Slots

“…During past 2 decades many methods have been proposed to enhance the bandwidth of microstrip antenna such as adding an impedance matching network, using slots, using stacked patches, edge-coupled parasitic patches, fractal patch or lossy materials [4,5,6,7]. Inserting a slot on the patch antenna can reduce the resonant frequency while reducing the dimensions of the antenna.…”
