The article provides a comprehensive discussion on the design details of the proposed antenna topology, thoroughly outlining the results from both simulations and experiments. Additionally, a comparison with past studies is included to offer a broader perspective on the performance characteristics of the antenna. The communication explores return loss, radiation characteristics and input impedance to ensure a deeper understanding of the antenna performance. The proposed design achieves a significant frequency reduction of 65.28 % compared to a reference antenna, highlighting its potential for short-range wireless communication at 434 MHz. In simulations, the measured efficiency is 65.36 %, while the antenna exhibits a corresponding 10 dB bandwidth of 1.25 %. The antenna topology consists of a compact printed monopole (0.086λ0 x 0.052λ0 x 0.002λ0) resonating at 434 MHz. Designed for reduced resonant frequencies, the antenna is suitable for short-range wireless applications at 434 MHz. Fabricated on an FR-4 glass epoxy microwave substrate, the lightweight and low-profile printed antenna utilizes a 50 Ω microstrip feed for excitation. To enhance the understanding of the antenna measurement configuration, the measurement setup for the antenna topology is provided. This article explored into the analysis of this antenna design, emphasizing its practical applications and advantages.
