Abstract
This research paper aims to design a new shape of the microstrip patch antenna. Combining a half circular and zigzag shape of a triangular patch antenna, we selected two different shapes of microstrip patch to obtained modern shape no one mentioned it before and it’s seems like a tulip rose, so this design achieved to works for multiband. The dimensions of the proposed antenna are (38×30×1.6) mm3 applied on the dielectric substrate FR-4, which has a relative dielectric constant of (εr=4.3) and loss tangent (tanδ=0.002). Both patch and ground are copper material with a thickness (t=0.035 mm). So four-band are achieved (5.1612-5.3874) GHz, (8.8729-10.067) GHz, (10.476-11.091) GHz, and (13.819-30) GHz. The return loss (S11) are (-20.784) dB, (-30.532) dB, (-19.246) dB and (-29.789) dB respectively. The antenna is printed by using FR-4 substrate and simulated by CST-Microwave studio software. This antenna works for various wireless applications such as Wi-FI, C band, X band, Ku band, Ka-band, cellular phones, and satellite communications.
Highlights
This paper presents a microstrip patch antenna with half circular patch and zigzag in the upper with one slot etched in the radiating patch to provide a multiband
Figure (2) shown the return loss (S11) results from we apply the calculation we gained from equation only, it’s appears not practical and not good results, so we made a parametric study
This work focuses on the design and simulation λ of a microstrip patch antenna
Summary
The interest in multi-band antenna is increasing, especially in order to limit the variety of antennas embedded in combining multiple functions in one antenna [1], [2]. To reduce the cost when used single antenna for worked in multiband. There are several methods for gaining multi-band [3], using model characterization from slots and fractals or etc. Recent wireless communication systems need to lightweight, low profile, high efficiency, high gain and simple structure [4]. The microstrip patch can take any shapes, circular and rectangular are commonly used , through the shapes that attracted recently is the triangular patch antenna shaped, The main advantage of made a multiband microstrip patch antenna for elimination the number of devices [6]. This paper presents a microstrip patch antenna with half circular patch and zigzag in the upper with one slot etched in the radiating patch to provide a multiband
