Abstract: An exponentially tapered slot antenna assembly includes a plurality of antenna panels arranged together in a general box-like configuration. At each corner of the box-like configuration, a capacitive load panel is in operative electrical communication with orthogonal pairs of antenna panels. Each antenna panel defines an inner and outer surface and has an electromagnetic interference shielding material positioned thereon. The shielding material positioned may be positioned near a first or upper edge of each antenna panel of the assembly. It has been empirically determined that this configuration enables an operational bandwidth that is greater than 5:1 and a voltage standing wave ratio that is less than 3:1 over the 5:1 bandwidth.

Abstract: The system and method for a tunable, slow-wave meander line antenna having a plurality of coplanar alternating high and low impedance traces. The tunable inverted L meander line antenna being suitable for space-constrained uses. Electronic switches, including solid state switches being used to tune the slow-wave meander-line inverted L antenna. Configurations of more than one antenna element providing polarization diversity, increased gain, and larger impedance bandwidths.
