Abstract

A wideband mono-cone antenna is proposed. Evolution from a top-loaded mono-cone, the top plate is etched by two rings and loaded by an array of resistors and inductors. This design improves impedance matching properties in the low frequency range while maintaining a compact size. An equivalent circuit modal is built for assisting the antenna design. A prototype is fabricated and measured for verification. The antenna operates in the frequency band of 118–1100 MHz with |S₁₁|≤-10 dB and the fluctuation of omni-directional radiation pattern ≤ 2.5 dB. The occupied area of the antenna is 0.24 λ_L × 0.24 λ_L × 0.06 λ_L, which is attractive for use on aircraft.
