| Popis: | This paper presents a 140 GHz corner-fed coplanar waveguide (CPW) square patch antenna and a three-element antenna array in embedded wafer level ball grid array (eWLB) technology. In both cases, the feed is provided by a 50 ohm CPW to one of the corners of a CPW square patch element. In addition, a ground plane reflector, realized on a separate Rogers 4003C based printed circuit board, is integrated with the eWLB antenna array using a ball grid array concept. This results in a planar superstrate antenna, whose bandwidth is several orders of magnitude larger than a usual edge-fed CPW patch antenna. The antenna characteristics are measured in D-Band using a probe-based measurement setup and compared with the electromagnetic simulation result. The antenna array shows a reflection coefficient of less than −10 dB and a realized gain of around 10 dBi over a broad bandwidth of 130 to 150 GHz. |
