Abstract EN
This paper presents a spiral antenna design operating in the frequency range of 1–15 GHz having both selective notch bands and wideband response.
The main feed arm of spiral antenna is configured as rectangular monopole of width quarter wavelength to achieve impedance matching with standard 50 Ω excitation.
Frequency tuning in the design is achieved by placing varactor diode at an appropriate position along the spiral arms and in the ground plane.
The design offers a peak gain of 3.4 dB (simulated) and 3 dB (measured).
The unique frequency response of antenna makes its suitable to be used for front-end system of cognitive radio for sensing the spectrum in various modes.
