Abstract :
Two simulated design examples are presented here to illustrate our proposed scheme. In the first example, the antenna element is a printed dipole antenna that produces a vertically polarized electric field. The design goal is to obtain a horizontal half power beamwidth (HPBW) of 90/spl deg/ /spl plusmn/ 5/spl deg/ and a F/B ratio greater than or equal to 30 dB in the frequency range of 800 MHz to 960 MHz. The radiation pattern of the resultant design 880 MHz is shown. The calculated HPBW is 89/spl deg/ at 800 and 960 MHz. The F/B ratios are 37.72 dB and 34.24 dB at the two frequencies, respectively. In the second example, a pair of cross dipoles are used as element for the array. These elements are commonly used in wireless communication systems to provide polarization diversity. The resultant electric field has components in both the vertical and horizontal directions.
