Abstract:

We present an ultra wideband UWB vertically polarized long slot circular phased array with a compact design for passive sensing applications Unlike conventional tightly coupled cylindrical systems that require multiple circular arrays our quasi magnetic current sheet array uses a single circular array while achieving similar radiated field properties A 16 element prototype demonstrates azimuthally invariant radiation capabilities Measurements indicate that the array offers wide impedance bandwidth high cross polarization discrimination XPD and significant compactness In its omnidirectional mode the array achieves a 107 07 bandwidth VSWR 2 0 with XPD better than 19 5 dB In its directional mode it operates over 100 bandwidth with XPD better than 20 9 dB The prototype also exhibits excellent azimuthal out of roundness better than 1 3 dB in its omnidirectional mode and scan invariant radiation with a maximum deviation of only 0 8 dB in its directional mode
