description An antenna for wireless communication comprises a dielectric substrate having a first side and an opposite second side. A first major arm having a first modified log-spiral spiral pattern is disposed on the first side of the dielectric substrate. A second major arm having a second modified log-spiral pattern is disposed on the second side of the dielectric substrate, wherein the first and second major arms are formed from a conductive material. A connector coupling is disposed at a center of the modified log-spiral patterns, the connector coupling having a first portion coupled to the first major arm and a second portion coupled to the second major arm. The antenna is self-complementary. The antenna can achieve a return loss better than 10 dB over a broadband range.
