Equilateral triangular microstrip patch antenna with spur lines embedded

Abstract

This paper presents an equilateral triangular microstrip antenna with spur lines. The proposed antenna, comprising a triangular planar patch element embedded with two spur line slots. The simulation and fabrication process are performed to understand the characteristics of the proposed antenna. The simulation result is compared with the fabricated antenna. The targeting frequency of this antenna is 0.90 GHz (first resonant frequency) and 1.80 GHz (second resonant frequency). The proposed antenna can improve the bandwidth of GSM 1800 up to 100 MHz. It shows the return loss of -16.176 dB, bandwidth of 33 MHz (0.919 GHz to 0.952 GHz) and a gain of 3.52 dB first resonant frequency. At second frequency, the return loss are -28.159 dB with a bandwidth of 115 MHz (1.714 GHz to 1.829 GHz) and gain of 3.380 dB.

High gain dual-resonance microstrip antenna

“…Another work uses same dielectric thickness and designs presents a high gain multiple resonance patch antenna in the Ku-band [10]. A probe-fed triangular shaped patch antenna, which uses symmetric slots, is presented in [11], where a parametric study similar to our work is conducted.…”

Design of Microstrip Line-Coupled Isosceles-Triangular Loop Resonator Antenna

“…In (Helszajn & James, 1978;Wang et al, 2003;Chen & Xue 2005;Nasimuddin et al, 2005), triangular patch resonator was investigated and reported. Shortly thereafter, microstrip triangular loop resonator was reported in (Lugo & Papapolymerou, 2005, Tautain et al 2001Zhao et al 2007) and since then various application using triangular patch is reported in (Saputra et al;Das et al 2013;Deshmukh et al 2013;Dam et al 2013;Malek et al 2013;Zulkifli et al 2013;Arulalaan & Nithyanandan 2013).…”
