Claims27
An antenna device including:
- a first conductive extended body structure including a first surface;
- a series of spaced apart conductive patches arranged substantially in the plane of a second surface offset from said first surface;
- a series of conductive feed interconnections capacitively coupled to the spaced apart array of conductive patches,
- said conductive feed interconnections being profiled to provide a complementary series inductance to said capacitive coupling so as to thereby improve the impedance matching of the conductive feed and conductive patches.

A method of designing an antenna array device, said device including a first conductive extended body structure including a first surface;
- a series of spaced apart conductive patches arranged substantially in a second surface offset from said first surface;
- a series of conductive feed interconnections electromagnetically coupled to the spaced apart array of conductive patches, the method including the step of:
- (a) providing a conductive patch pattern that increases the conductive patch inductance in comparison with a checkerboard or self complementary array when said antenna array device is operated at frequencies greater than that at which the distance between the first and second surface is a quarter of the wavelength.
23-24. (canceled)
A method of suppressing the amount of common mode current in an antenna array device, said device including a first conductive body structure including a first surface;
- a series of spaced apart conductive patches arranged substantially in a plane of a second surface offset from said first surface;
- and a series of conductive feed interconnections electromagnetically coupled to the spaced apart array of conductive patches, the method including the step of:
- suppressing the common mode current by shielding said conductive feed interconnections in the vicinity of said first conductive body structure sheet.
