Objective

o design a compact broadband antenna with improved impedance matching and bandwidth. It aims to utilize slot loading and high-pass matching techniques to enhance performance while minimizing size. Additionally, the objective is to ensure efficient and reliable operation for modern wireless communication applications

Abstract

This project presents the design and analysis of a broadband miniaturized blade monopole antenna optimized for wideband airborne and communication applications. The proposed antenna achieves efficient operation in the 30–800 MHz frequency range by integrating geometrical modifications and circuit-level matching techniques. A tapered blade structure with optimized height and width improves impedance bandwidth while maintaining a compact profile suitable for low-drag, airborne installation. To further enhance low-frequency performance, a slot is introduced in the radiating element, which increases the effective electrical height and improves impedance characteristics. The slot is loaded with a series resistor–inductor (R–L) network, which effectively flattens the voltage standing wave ratio (VSWR) response in the 240–324 MHz band. Additionally, a lossy high-pass matching network is employed to extend impedance matching below 88 MHz, compensating for the inherently small electrical size of the radiator at lower frequencies. Full-wave electromagnetic simulations demonstrate that the antenna achieves a VSWR less than 2 across the target band, with realized gain varying from –28 dBi at 30 MHz to 5.6 dBi at 800 MHz. Radiation patterns remain largely omnidirectional in the azimuth plane, making the antenna suitable for broadband communication systems requiring compactness and wide coverage.

Keywords: Broadband antenna, blade monopole, slot loading, high-pass matching network, wideband communication, airborne applications, VSWR.
