In some embodiments, the dual mode antenna 1206 may be a MEMS antenna. For example, in embodiments where the dual mode antenna 1206 is configured to receive RF signals in a range of 50-70 GHz and transmit RF signals in a range of 100-140 GHz, the dual mode antenna may be realized as a MEMS antenna. The MEMS antenna may be fabricated on the semiconductor substrate 1202 using any suitable semiconductor fabrication process(es) (e.g., deposition, etching, lithography, patterning, etc.). It should be appreciated, however, that the dual mode antenna 1206 is not limited to being a MEMS antenna and may be a larger physical structure, manufactured separately from the substrate 1202, as the case may be in embodiments where the dual mode antenna is configured to receive/transmit RF signals at lower frequencies (requiring larger wavelengths and, therefore, a larger antenna). For example, in some embodiments, a dual band antenna configured to receive RF signals in a range of 4-6 GHz and transmit RF signals in a range of 8-12 GHz may be manufactured separately from the substrate 1202 (e.g., without using semiconductor fabrication techniques) and subsequently be mounted on substrate 1202. Such an antenna may be fabricated from any suitable material such as, for example, aluminum or brass. In some embodiments, the dual band antenna may be a patch antenna and/or a planar antenna.
