This paper explores the analysis of a low-profile, lightweight patch antenna fabricated on an FR-4 glass epoxy microwave substrate using a 50 Ω microstrip feed. This antenna is organized for reduced resonant frequencies, making it suitable for short-range wireless communication at 315 MHz. The antenna topology discussed a compact a meandered patch (0.0860 0.0730 0.0020) resonating at 315 MHz. This antenna exhibit corresponding bandwidth (10 dB) 14.46 %. In simulation, the efficiency is measured at 89 %. Compared to a reference antenna, the design achieve significant frequency reduction of 86.48 %, indicating the potential for short-range wireless communication systems operating at 315 MHz. This communication also discusses return loss, radiation characteristics and input impedance to provide a comprehensive understanding of the antenna performance. The design details of proposed antenna topology, along with results from simulation and experiment, is outlined and discussed thoroughly. Additionally, a detail past study is included to offer a more comprehensive perspective on the antenna performance characteristics. |
