Design of Ku Band Downlink Array Antenna with SiO2 Substrate for Gain Enhancement

The antenna arrays are used to overcome the limitations of single antenna. In this work a linear array of six array elements are proposed on a glass substrate with a defective ground plane is proposed. Each element is considered in H shape. Glass (SiO2) is chosen for substrate due to its high permittivity of 5.5. The dimension of the antenna structure is considered as 40X98X0.675mm3. The elements are fed through a corporate feed arrangement. The antenna resonates at 12.8GHz, 14GHz and 14.6GHz with gain of 9.6dB, 13.2dB and 8dB respectively. The resulted frequencies satisfy the Ku band communication
