A new class of electromagnetically coupled printed antenna arrays

A new class of electromagnetically coupled microwave printed antenna arrays using three coplanar strip-TCS (CPW with finite narrow ground strips) is reported. Two versions of this antenna array are introduced. (1) Antenna array with practically pure omnidirectional radiation pattern in horizontal plane, vertical polarization and gain of 8 dBi. (2) Directional antenna with gain of 14 dBi. Both versions are designed for frequency of 10.5 GHz.
