An antenna device 601, or a method of making an antenna, comprises: a first layer which includes at least two antenna branches 603, 604 separated by a separation area and a second layer 607 which comprises a ground plane below the at least two branches 603, 604 with a non-conducting part 605 disposed below the separation area. The separation area may be a rectangular shape and the non-conducting part 605 of the ground plane 607 may be a slot with an area which is 1 to 4.8 times that of the separation area. A metal track 606 may be formed in the slot 605, which is isolated from the ground plane 607. The first and second layers may be made of metal which are separated by a dielectric layer. The antenna branches may be separated by a distance of a quarter to a half wavelength of an operating frequency of the antenna. The antenna arrangement may also include an electromagnetic radiation focusing lens 608. The antenna arrangement may be formed in a printed circuit or a CMOS integrated circuit. A communication device comprising a field effect transistor (FET) combined with the antenna arrangement may be used to provide a low thickness, efficient, microwave to Terahertz frequency operational arrangement suitable for recovering a signal sampling frequency. |
