Abstract :
A patch antenna is an excellent choice for wireless, vehicular and other advanced communication applications. We describe a central-feeding scheme which is a useful antenna arrangement to obtain two band responses where space is a constraint, with good isolation between the two bands. Good impedance matching of less than -10 dB was obtained at the two frequencies with no large pattern imbalance. This new method of feeding has a potential advantage for use in communication receivers, in feed arrays for illuminating reflectors, and in communication vehicles for remote sensing applications. With a variation in the feeding method, dual-polarization and array configurations can be incorporated.
