A multiband microwave antenna () is described, which antenna is intended particularly for surface mounting (SMD) on a printed circuit board (PCB) and has a substrate () having at least a first and a second metallization structure (), wherein the first metallization structure () has at least a metal area () forming a resonator area and the second metallization structure () has at least a resonant printed conductor structure (), thus enabling the antenna to combine the advantageous properties of a PIFA (planar inverted F-antenna) with those of a PWA (printed wire antenna).

Multiband microwave antenna

The invention relates to a miniaturized phased array antenna with a plurality of individual radiator elements (10xy), which antenna is designed in particular for use in the microwave frequency range. The antenna is characterized in particular that the radiator elements (10xy) are each aligned in dependence on their positions in the array so as to achieve a current distribution over the antenna as determined for a desired antenna characteristic. This renders it possible to realize a very strongly miniaturized antenna without the efficiency of the antenna being appreciably reduced.

Phased array antenna

A description is given of a miniaturized directional antenna with a ceramic substrate ( ) having at least one resonant printed wiring structure ( ), in particular for use in the high-frequency and microwave ranges, which antenna is particularly suitable in that an electrically conductive motherboard ( ) is provided on which the substrate is arranged, while the at least one printed wiring structure ( ) extends with one end as far as the motherboard. A radiation characteristic directed largely only in a half-space is achieved thereby.
