Analysis and design of a 3.5-GHz patch antenna for WiMAX applications

Abstract

A high-gain microstrip patch-type WiMAX antenna operating at 3.5 GHz has been designed with a parasitic radiator and a raised ground plane. Antenna design has been carried out through extensive three-dimensional electromagnetic simulations. The patch antenna itself provides a realized gain of about 3.6 dB at 3.5 GHz. When a parasitic radiator is placed on top of the patch antenna, the gain increases from about 3.6 dB to about 7.4 dB. The raised ground plane further enhances the gain by about 1.5 dB. Hence the overall gain improvement is about 5.3 dB without the need of a radio-frequency amplifier.

An ultra-thin, dual band, Sub 6 GHz, 5G and WLAN antenna for next generation laptop computers

“…From the table, the salient features of the antenna are as follows: The proposed antenna is simple in design and cost effective, unlike Pazin and Leviatan (2011) and Pazin et al (2010), and takes very less time to market. The antenna is designed without using reactive components, unlike Su (2018) and Kang and Wong (2010), additional circuit, unlike Pazin et al (2010) or matching circuit (Abioghli, 2011). Very small in size as compared to Kim et al (2011), Xu et al (2012), Liu et al (2015) and Cirik and Yildirim (2014). Ultra-thin antenna as compared to Khan (2017), Abioghli (2011), Xu et al (2012) and Bartwal (2016). Suitable with other portable devices, unlike all the reported state of art as it performs equally well with different sizes of system ground. The gain and efficiency of the proposed antenna are above 5 dBi and 83% respectively, unlike Su (2018), Khan (2017), Sim (2017) and Bartwal (2016). …”

“…To confront the bandwidth requirement of WLAN and 5G in the laptop computer, the development of multiband antennas with simple structure, low cost and easy manufacturing with excellent performance has drawn considerable attention all over the world. The different multiband antennas including monopole antenna (Su, 2018), folded monopole (Kim et al , 2011), multiband monopole (Khan, 2017), printed monopole antenna (Abioghli, 2011; Sim, 2017), monopole antenna with chip inductor (Kang and Wong, 2010), strip monopole (Chung et al , 2009), Coplanar waveguide-fed monopole (Xu et al , 2012; Chaimool et al , 2009; Yu and Wang, 2009; Yu, 2014), meandered monopole antenna (Zaman and Ahmad Haris Mehmood, 2017; Bartwal, 2016), clover leaf monopole (Hong and Lee, 2012), polarized antenna (Brar et al , 2018; Tang and Wang, 2017), broadband antenna (Chen and Peng, 2009; Liu et al , 2015), uni-planar antenna (Chou and Wong, 2007), inverted-F antenna (Pazin and Leviatan, 2011; Pazin et al , 2010), microstrip antenna (Singh Bakariya et al , 2014) and patch antenna (Cirik and Yildirim, 2014) have been reported recently.…”
