Improved bandwidth low-profile miniaturized multi-arm logarithmic spiral antenna

No / A low-profile (λ/43) miniaturized multi-element antenna is presented, which displays vertical polarization with an omni-directional radiation pattern. The antenna uses a logarithmic spiral shape as the main radiating element such that the impedance bandwidth of the antenna is much improved in comparison with both a strip-line square spiral design and a strip-line circular spiral design. The antenna demonstrates stable gain and useful efficiency over the operating frequency band. Significantly, the antenna provides a low profile, omnidirectional pattern in the azimuth plane, polarizes normal to the ground-plane with a 1.2% bandwidth and 0.5 dBi gain.
