Abstract
A broadband coplanar waveguide fed butterfly shape slot antenna is presented in this paper. The designed antenna operates in the frequency range from 1.89 to 5.21 GHz (93.5%) for S11 ≤ −10 dB with a broadside gain of 5 ± 1 dBi over the bandwidth of 1.97–5.19 GHz (90.3%). The designed antenna is uniplanar having the size of 0.5 λ0 × 0.28 λ0 × 0.005 λ0 (λ0 is the wavelength at the lowest operating frequency in free space). The proposed configuration has a stable radiation pattern over the operating frequency band. The designed antenna is fabricated and simulated results are validated with measured results.
