A single layer dual-polarization printed bow-tie broadband antenna

A single layer dual-polarization coplanar waveguide (CPW)-fed bow-tie slot antenna for broadband communications is proposed in this literature. The proposed antenna has a very simple antenna structure and wide impedance bandwidth (~400% for|S11|and|S22|≤ -10dB) which can cover the 1.5 ~6 GHz frequen...

Description
Summary:A single layer dual-polarization coplanar waveguide (CPW)-fed bow-tie slot antenna for broadband communications is proposed in this literature. The proposed antenna has a very simple antenna structure and wide impedance bandwidth (~400% for|S11|and|S22|≤ -10dB) which can cover the 1.5 ~6 GHz frequency band for Global Positioning System (GPS, 1575MHz) and dual ISM band (2.4GHz and 5.8GHz) applications. Good isolation between the two input ports (|S21|≤ -20dB) is also achieved at the operating band. The radiation pattern and efficiency of the proposed antenna are also measured, and radiation pattern data are compared with simulation results.
