A Patch Antenna design with Boosted Bandwidth for ISM band Applications

Abstract

In recent times, the utilization of microstrip patch antennas (MPAs) has increased due to their simple production, simple analysis, low cost, lightweight, easy feeding, and superior radiation characteristics. Limited bandwidth is a key disadvantage of MPAs. In this paper, a rectangular patch antenna with partial ground plane (PGP) strategy for ISM applications is proposed to overcome this deficiency and its performance is compared with that of a traditional patch antenna. A low-cost FR-4 substrate with a dielectric constant of 4.3 and a thickness of 1.6 mm is used to make both antennas designed. The antennas are analyzed and simulated at the operating frequency of 2.45 GHz using CST software. The simulation results show that the proposed antenna has a 0.1465 GHz i.e. 146.5 MHz bandwidth, which is more than 1.77 times larger than a conventional antenna (bandwidth = 0.0827 GHz i.e. 82.7MHz). The suggested antenna is suitable for a wide range of wireless communication standards, such as Bluetooth (2.4 to 2.485 GHz), WiMAX (2.3 to 2.4 GHz), Microwave ovens (2.4 to 2.48 GHz), RFID (2.4 to 2.5 GHz), S-Band (2.3 to 2.4 GHz), Wireless Communication Services (WCS) 2.345 GHz to 2.360 GHz, and 4G LTE (2.3 to 2.315 GHz).

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

“…Microstrip patch antennas present numerous advantages, rendering them widely favored across diverse applications. 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].…”

“…The issue of narrow bandwidth holds significance due to its impact on antenna performance, thus underscoring the importance of the Qfactor as a pivotal parameter for design assessment [21]. In response to the bandwidth constraint, innovative approaches like incorporating partial ground planes have been proposed, significantly augmenting bandwidth for specific applications [19]. Furthermore, enhancing both bandwidth and gain is imperative for optimizing the performance of microstrip patch antennas within wireless communication systems, thereby driving the development of broadband designs endowed with superior characteristics [13].…”
