Abstract

A modified microstrip combline array antenna (MMCA) is designed to obtain wide beamwidth (≈90°) in E-Plane radiation pattern and therefore the better coverage for using in the radio controller systems for avionic application. Beside wide beamwidth, wide bandwidth can be obtained by designing of MMCA in travelling wave mode. Moreover, as will be seen in the paper, to achieve a better performance we need the low sidelobe level and tilted radiation pattern, which can be obtained by suitable tapering the amplitudes of array elements and adjustment the phase difference between them, respectively.
