Dual Band Edge Wall Slotted Array Antenna with Reduced Cross Polarization at X Band

摘要

A novel dual-band edge-wall slotted array antenna with reduced cross-polarization is proposed for X-band applications. A new vertical wrap up has been used with narrow wall slots for designing the array. Two frequencies of resonance are observed at 8.64GHz and 10.10GHz respectively with suitable matching performances. Metallic flares are introduced on both the sides of the waveguide for the purpose of reducing the cross-pol radiation and the results are compared. A reduction of around 10dB in the cross-pol levels are observed due to the inclusion of the additional flares. The simulated gains at both the frequencies of operation were found to be 16.79dB at 10.10GHz frequency and 15.39dB at 8.64 GHz frequency- which demonstrates that the proposed antenna can be used for dual band applications.
