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).
