Design of Dual-band Coupled-fed Dipole Array Antenna Element for PCL Systems

초록

This article proposes a dual-band coupled-fed dipole array antenna element fir Passive Coherent Location (PCL) systems, which is operating in FM and T-DMB bands. The proposed coupled-fed antenna is composed of the internal and external dipoles that resonate in FM and DMB frequencies, respectively. To confirm the suitability of the proposed coupled-fed antenna, we construct an 8-element uniform circular array (UCA) with the proposed coupled-fed dipole element and examine the beamforming performance of the array. The results verify that the proposed antenna structure can achieve the required dual-band operation for PCL systems using the coupled-fed mechanism.
