Abstract:
A communication antenna comprising:a driven element extending between a feed point (13) and an attachment point (15) to a top loaded element; the driven element (16) having a length and the length of the driven element (16) being greater than a straight path distance (P) between the feed point (13) and the attachment point (15); and the driven element (16) being configured to follow a meandering path between the feed point (13) and the attachment point (15); wherein the communication antenna is equipped with at least one pair of parasitic elements (18, 19), and each one of the at least one pair of elements has at least one member and each of the at least one member of the at least one pair of elements are disposed on opposite sides of, and off-set from, the driven element (16) but parallel to the straight path (P) linking the feed point (13) to the attachment point (15); and the parasitic elements (18, 19) serve to provide impedance matching and increased bandwidth while also serve to at least partially shield against radiation from the antenna (10).
