ABSTRACT:
An antenna assembly (700) includes a set of conformal shells (704, 706) housing a set of orthogonal dipoles (102, 104, 108, 110) that produce a circularly polarized radiation pattern. The dipoles (102, 104, 108, 110) are fed by a quadrature hybrid (118) and impedance matching circuit (114). The assembly (700) also includes a set of baluns (126, 128) to reduce VSWR.
