Design and Analysis of Meander Microstrip Antenna at Wireless Band

Abstract

Meander line antenna (MLA) is an electrically small antenna which poses several performance related issues such as narrow bandwidth, high VSWR, low gain and high cross polarization levels. This paper describe the design ,simulation and development of meander line microstrip antenna at wireless band, the antenna was modeled using microstrip lines and S parameter for the antenna was obtained. The properties of the antenna such as bandwidth, beamwidth, gain, directivity, return loss and polarization were obtained.

A novel meander line integrated E-shaped rectenna for energy harvesting applications

“…Pasakawee and Hu presented an electrically small patch antenna using meander lines and CSRRs on the ground plane causing the reduction of the antenna size. In a different study, Ogherohwo presented a 2.4 GHz meander line antenna and Zainuddin used a meander lines slot on the patch antennas with different numbers in diverse positions and achieved maximum 23% size reduction in his application. Ghadimi used a rotated E‐shaped strip in patch antenna and embedded an interdigital strip filter for the harmonic rejection and obtained maximum conversion efficiency of 74% with 1 Kohm load resistor for a low power rectenna.…”

“…In terms of operating frequency, have the multifrequency operation mode, on the other hand, Refs. , has a single frequency feature. The proposed antenna has the single band operation as in above‐mentioned antennas.…”

“…In terms of the gain, and proposed antenna nearly at the same level of the gain; however, has a low level of gain, Refs. have the maximum gain values of 6‐6.5 and 4, respectively, at the operation frequency. In terms of the bandwidth, proposed antenna has the highest one and it is followed with 270 MHz bandwidth by Ref.…”

Meander‐line‐based defected ground microstrip antenna slotted with split‐ring resonator for terahertz range

“…The side view of a conventional patch antenna is shown in Figure A. A meander‐line geometry is shown in Figure B where the horizontal lines are acting as capacitor and vertical lines as inductor …”

“…The power of this terahertz antenna is fed through the feed line in the optical range having an impedance of 50.06 Ω so that it is convenient to feed by SMA connector of 50 Ω impedance . The resonant frequency and other characteristics mainly depend upon the horizontal and vertical length of the meander line along with the separation between the twist arms, wire width, and the total physical length of the antenna . Besides that, the resonant frequency is also controlled by the shapes and dimensions of the SRR, which are the functions of capacitance and inductance .…”
