Abstract

A novel differential-fed dipole antenna with compact size is proposed and investigated. The size of the antenna is only 0.8λ0 × 0.8λ0 × 0.13λ0 (where λ0 is the free-space wavelength at the centre frequency). By utilising a pair of complementary sources, the antenna achieves good unidirectional radiation performances. The antenna has an impedance bandwidth of 38.5% for SWR , 2 from 1.63 to 2.4 GHz. The boresight gain ranges from 7.8 to 9.6 dBi. The cross-polarisation level is lower than -25 dB while the front-to-back ratio is above 12 dB across the operating frequency band. Moreover, the antenna is simple structured and easy to be fabricated.
