The dipole antenna design is one of the two options looked at for the antenna design in the EECE 690/890 Digital Radio Receiver. The other option considered was a loop antenna design. The designs also need to include a matching network to match the antenna to a 1k to 2k ohm load.
Design Requirements: Must be compact in size, with a goal of integrating the antenna on-chip. The chip will be approximately 2 mm x 2 mm. The frequecny of operation is centered around 2.44 GHz. The antenna must have a reasonable efficiency. Initial design should include measurement points for observing antenna performance. The antenna design needs to include a matching network for at least a 1 kohm load.
Best Design: The best design found was a dipole set in a corner of the chip that was extended using bondwires to include the leads of the chip packaging. Not only does this design present an efficient solution to the problem, it provides the most flexible research capabilities. The antenna can be tested as designed (using the packaging), or as integrated antenna with the bond wires removed. Also the antenna could be lengthened using the packaging leads. To further improve the testing performance the matching network was broken into two parts: One part increased the impedence of the antenna to 50 ohms for testing purposes and another increased the impedence up to 1 kohm.
