Ultra Wideband Rose Leaf Microstrip Patch Antenna

Abstract

In this paper a novel rose leaf shape microstrip antenna with capacitively coupled rectangular fed is presented. Various shapes of capacitive coupled fed are compared and optimized by successive iterations of a computer-aided analysis. The Ansoft HFSS is employed for analysis at the frequency band of 4.3 GHz-8.3 GHz. The antenna is fabricated and measurement results show a very good agreement with the simulation results. The proposed antenna is able to achieve an impedance bandwidth about 69%. Effects of varying the parameters on the performance of the antenna have also been studied. The proposed antenna can be used in wireless ultra-wideband (UWB) communication.

Parametric Study of Printed Monopole Antenna Bioinspired on the Inga Marginata Leaves for UWB Applications

“…This technique proposes a rectangular opening (slit) in the ground plan with L S and W S dimensions. The lowest frequency of PMA can be approximated by (1), where p is the perimeter of the radiating patch and is the effective relative permittivity of the dielectric [2].…”

A Novel UWB Monopole Antenna with Defected Ground Structure

“…Those include compact size, lower profile, and simpler structure, which lead to lower costs, easy fabrication, and convenient integration with monolithic RF circuits. The performance of the UWB antennas in both time and frequency domain are of equally importance which makes the UWB antenna design a challenging and interesting field of research [2][3][4][5]. As the key component of the UWB wireless communication system, the UWB antenna has drawn increasing attention [6].…”

A Monopole Microstrip Antenna With Enhanced Dual Band Rejection for Uwb Applications

“…UWB digital communication systems which uses an extremely wide frequency range are meant for providing radio communication at low power with high bit rates [1][2][3][4][5]. The performance of the UWB antennas in both time and frequency domain are of equally importance which makes the UWB antenna design a challenging and interesting field of research [6][7][8][9][10][11][12][13][14]. An excellent UWB antenna is one which can transmit and receive the frequencies over the bandwidth designated by FCC [1,2].…”
