Miniaturised printed monopole antenna with a linked ground plane and radiator

Abstract

A novel miniature wideband microstrip antenna is presented. The proposed miniature design is achieved by exploiting the idea of a quasi-radiator. Here, a part of the radiator is connected to the ground plane through a shorting pin or via. The proposed antenna achieves a starting frequency of 1.8 GHz with a small antenna area of 20 mm 2. An electrical size of 0.05λ is realised leading to a miniaturised design. The proposed antenna is broadband, compact, and produces stable radiation patterns.

A Novel Printed Monopole Antenna With Folded Stepped Impedance Resonator Loading

“…With the development of integrated circuit and component technology, the size of these devices is decreasing, and the demand for antenna integration is increasing. In recent years, design methods of printed monopole antennas with various structures have been proposed [3][4][5][6][7][8][9][10]. For instance: tapered meander line [3], folded meandering branches [4], half-cutting method [5], shorted pin connecting ground [6], meandered split-ring slot [7], loading rectangular patch [8], and coplanar waveguide (CPW) feeding monopole antenna [9,10].…”

Design of CPW-fed Star-Shaped Monopole Antenna for UWB Applications using Transmission Line Model

“…The wideband impedance bandwidth is achieved by using space-filling concepts, different fractal antennas, CPW-fed antennas with dual-reverse-arrow fractal structure, flexible bow-tie slot antenna, a rose-curve shape monopole antenna, wideband fractal shapes structure, and tapered slot antenna [4]- [10]. To achieve wider bandwidth and better impedance matching a semi-circular patch [11], quasi-radiating patch [12], modified meandered slot [13], microstrip-fed parasitic-coupled monopole hybrid design [14] and optimized surrogate-based patch [15] are proposed. However, the monopole antennas mentioned above have a large physical size and the complex geometry to realize in the required operating frequency bands.…”

A Novel Printed Monopole Antenna With Stepped Impedance Hairpin Resonator Loading

“…With the rapid development of wireless communication technology, how to design a multi-function, low profile and omnidirectional wireless communication antenna has become the focus of many engineers [1]. So far, several research reports have been presented on printed monopole antenna [2]. In [2], a part of the radiation patch of the printed monopole antenna is connected to the ground through a shorted pin to realize a printed monopole antenna.…”
