wound wire portion 22 an opposite shorting end 32 of the wire 28 is shorted to the ground plane board 12 as will be disclosed in detail further herein the antenna 10 formed with the helically contoured member 18 attached to the dielectric block 14 and secured on the ground plane board 12 is coupled to the sma connector 38 through a feeding pin 40 a shorting pin 42 is provided on the ground plane board 12 for shorting the antenna thereto the ground plane board 12 is a printed circuit board pcb made for example by fr4 with a copper plate embedded as a layer inside the ground plane board 12 has an opening 44 serving as a passage for the feeding pin 40 and an opening 46 at which the shorting pin 42 is soldered for different modifications of the compact antenna 10 in question the pcbs 12 of different dimensions can be used all however are compatible with ultra low volume smart dust applications as an example table 1 represents parameters for the pcb 12 used for 2 2 2 45 ghz antenna the dielectric block 14 serves as a supporting block as well as for the reduction of the overall volume occupied by the compact antenna in question preferably the dielectric block.
