Abstract-Planar coaxial fed wideband printed dipole antenna
is designed to satisfy DTV signal reception needs. This antenna
consists of two asymmetric loops separated by step shape feed
gap. These loops contains two inner loops which are connected
to external loops with the help of rectangular coupling patches.
Two resonant modes are excited due to the length of the
antenna and length of step feed gap. Operating bandwidth is
enhanced due to the addition of the inner loop and coupling
patch. Various parameters such as bandwidth, return loss,
antenna gain, and radiation efficiency of proposed antenna are
simulated and discussed. The simulated radiation pattern is
omnidirectional matching to the conventional dipole antenna.
The proposed antenna has an antenna gain varying from -8 to
-10 dB and operating bandwidth is found to be 470-925 MHz
with return loss better than 7.35 dB. Therefore, the proposed
antenna is very much compatible to digital television signal
receiving applications.
