Slot antenna having a MEMS varactor for resonance frequency tuning
First Claim
1. An apparatus, comprising:
- a antenna layer having a primary slot formed entirely within the antenna layer, the primary slot not touching an edge of the antenna layer;
one or more secondary slots formed entirely within the antenna layer to form a slot antenna, the one or more secondary slots each having a perpendicular intersection crossing the primary slot, the secondary slots not touching an edge of the antenna layer; and
one or more varactors coupled to one or more of the secondary slots and not connected across said perpendicular intersection, to tune the slot antenna to a desired frequency via selection of a capacitance of one or more of the varactors.

Abstract
Briefly, in accordance with one embodiment of the invention, a slot antenna may include a primary slot and one or more secondary slots. The size of the antenna may be reduced by adding one or more of the secondary slots which may add additional inductance to the antenna. Furthermore, the size of the antenna may be reduced by increasing the inductance of the secondary slots via increasing the length of the slots or by changing the shape of the slots. The antenna may include one or more MEMS varactors coupled to one or more of the secondary slots. The resonant frequency of the slot antenna may be tuned to a desired frequency by changing the capacitance value of one or more of the MEMS varactors to a desired capacitance value.
