Abstract :
A wideband magneto-electric dipole antenna is designed. The antenna is composed of a horizontal bowtie electric dipole and a vertically-oriented folded shorted patch antenna. Simulated and measured results are presented which reveal that the antenna can achieve an impedance bandwidth of 95.2% (SWR≤2), stable unidirectional radiation pattern with low cross polarization, low back radiation, nearly identical E- and H-plane patterns and a stable gain over the operating frequencies.
