Comparison of performance characteristics of rectangular, square and hexagonal microstrip patch antennas

Abstract

The recent developments in the era of low-cost and compact communication systems have largely been due to the advent of small weight and size antennas that are capable of giving good output characteristics over a large frequency range. Microstrip patch antenna has become very famous and has attracted much attention towards the research because of these reasons. In this paper, the comparison of three widely popular designs of microstrip patch antennas has been done. Designing begins with the design of patches and then its analysis. Rectangular, square and hexagonal micro strip patch antennas are analyzed using HFSS and a comparison is made between them. In addition to low computational complexity, enhanced connectivity and high speed, modern wireless communication networks also offer advantages such as low profile structures, lightweight, gain must be high and compact size that assures reliability, mobility, and good efficiency. The compact design of patch antennas is due to conventional micro-strip fabrication technique.

Circularly Polarised Hexagonal Patch Antenna With Polygonal Slot for RFID Applications

“…The RHCP helical antenna gives more output when tested with RHCP under study and vice versa. Graphs plotted in Figure 7 confirm the directions of sense of polarization of the LHCP and RHCP antennas under study Hexagonal shape is preferred for the antennas because it has more bandwidth compared to rectangular and circular patches [15].…”

“…More impedance bandwidth is due to the choice of feed location and shape of the patch. The authors have experimentally proved in [14] that when the patch shape is dodecagonal gain is slightly less (4.82 dBi -4.67 dBi) , ARBW is 5.5 % and when the shape is hexagonal with elliptical and circular slots the gain is 4.5 dBi and ARBW is 5.8% [15]; both designed for the same resonant frequency 2.45GHz.…”

Performance comparison of 60 GHz printed patch antennas with different geometrical shapes using miniature hybrid microwave integrated circuits technology

“…This comparison deals with almost all of regular geometric shapes of the microstrip patch at 60 GHz band including rectangular, square, triangular, trapezoidal, circular, elliptical, and annular ring. It provides a more complete view compared with other works in the literature that most of them are focused only on the more common microstrip antenna shapes such as the rectangular and circular shapes [10][11][12]. One of the important considerations in designing the proposed microstrip patch antennas is the compact size.…”

Rectangular Patch Antenna Array Slotted Design for Triple Band Using HFSS

“…But, stability is still one of the important properties of coming up application [6]. Microstrip patch antenna is the most suitable and prevalent type of antenna in use today, their effective frequency range is in between 1GHz to 10 GHz.…”

“…These antennas find applications in mobiles instruments, receivers using GPS technologies and other wireless and wired products reason being there high values of dielectric constant and additional size reduction. Since this antenna has flat profile and is light in weight also makes them suitable for applications like airborne and spacecraft [6].…”
