Broadband Microstrip Antenna Overview

Abstract

Microstrip antennas are widely used in people's daily life. Microstrip antenna has the advantages of low cost, low profile, small space occupation, and high conformal capability. So the design of microstrip antennas can be encountered in daily life. Microstrip antennas include the military, aerospace, medical, and so on. Microstrip antenna has a wide research space. The three microstrip antennas, U-shaped open slit laminated microstrip antenna, dual frequency circularly polarized laminated microstrip antenna, and non-radiating edge-fed broadband double-layer microstrip patch antenna are mainly introduced to understand the research progress and expectation of today's microstrip antennas. This paper firstly introduces the basic theoretical concept of microstrip antenna, then introduces the cavity mode theory, and then mainly lists and introduces three kinds of designed microstrip antenna structures. Finally, these three types of microstrip patch antennas are analyzed. And the advantages, disadvantages, and development fields of the corresponding types of microstrip patch antennas are introduced. The application determines the structure of the method used, and each design has its strengths. Microstrip antennas always have room for research, and continuous research will be applied to more fields.

Design and Optimization of Microstrip Patch Antennas for Wireless Communication Systems– A Literature Review

“…Microstrip Patch Antennas are structured with a conducting material patch affixed onto a dielectric substrate, supported by a ground plane beneath [1,9]. These antennas are characterized by their lightweight, sleek profile, and effectiveness in radio wave transmission and reception [10].…”

“…Renowned for their straightforward analysis, cost-effectiveness, lightweight construction, and appealing radiation characteristics [5,18], these antennas boast compactness, low profile, and exceptional conformal capability, rendering them suitable for a broad spectrum of domains including military, aerospace, and medical applications [19]. With the capacity to deliver commendable gain, broad bandwidth, and efficient performance across varied frequency spectrums, microstrip patch antennas adeptly fulfill the requirements of contemporary wireless communication systems [9]. Furthermore, ongoing advancements in microstrip patch antenna design have yielded enhanced performance, positioning them as a promising choice for forthcoming communication systems, potentially extending to applications within 6G technologies [3].…”

A review of 2.45 GHz microstrip patch antennas for wireless applications

“…The following year, 1981, the IEEE Antennas and Propagation Journal issued a special issue on microstrip antennas in January. This publication established microstrip antennas as a specialized branch within the subject of antennas [9]. The microstrip antenna is a piece of equipment that can change the form that electrical power takes into that of an electromagnetic wave and vice versa.…”
