Abstract

A small volume antenna (100) has the form of a polygonal (e.g., square) board with multiple antenna elements (104, 110) located at vertices (114, 116) (e.g., opposite vertices). The antenna elements (104, 110) include two segments (118, 120, 124, 126) that meet at corners (122, 128) that are located at the vertices (114, 116). Peripheral portions (134, 136, 138, 140) of a ground plane (132) that underlie the segments (118, 120, 124, 126) of the antenna elements are deleted, and slots (154, 162) that have two joined segments (156, 158, 164, 166) that parallel the segments (118, 120, 124, 126) of the antenna elements (104, 110) are formed in the antenna elements. The antenna elements (104, 110) are selectively loaded by switched impedance (e.g., capacitance) networks (172, 176, 178, 180, 182, 186, 190, 192). The antenna (100) is able to support operation in at least two broad operating bands.
