Abstract / Description of output

The design and operation of a compact antenna array offering circularly polarized (CP) radiation for picosat and other small satellites for communication applications is presented. The proposed array combines folded-shorted patches (FSPs) and meandering for antenna miniaturization. Realization of CP is achieved by a compact and planar feed circuit consisting of a network of meander-shaped 90- and 180-degree hybrid couplers which can provide quadrature feeding of the FSP elements and can be integrated onto the backside of the antenna ground plane which is only 5 cm by 5 cm. Agreement in terms of the simulations and measurements is observed with realized gain values of more than 3 dBic at 1.065 GHz and with an antenna size of ${0.17\lambda 0}$ by ${0.17\lambda 0}$ .
