Abstract

In this paper the design of asymmetric wideband printed dipole antenna is presented along with measured results. The wide bandwidth covering 0.8-4 GHz is achieved using inset feeding technique. This paper also presents the techniques for achieving good omni-directional radiation patterns over the wide frequency band with deviation from omni-directionality within ±2.5 dB. This design offers more than 5:1 impedance bandwidth (for VSWR≤2.2:1), with good radiation efficiency and omni-directionality. The comparison study of symmetrical and asymmetrical printed dipole antennas with and without inset feed is presented in this paper. Thus, the proposed antenna finds a wide range of applications in trans-receive modes in today's wireless devices.
