ABSTRACT:
A wideband monopole antenna arrangement, for a portable communication device, includes a substantially continuous conductor plate that includes a first antenna element and a second antenna element, and a signal ground arranged to interact with the antenna elements so as to form the wideband monopole antenna arrangement. The first antenna element extends substantially at an angle (θ) with respect to the second antenna element. The angle (θ) forms an acute angle of a right-angled triangle (T) in which the first antenna element extends substantially parallel to a hypotenuse (h) of the triangle (T) and the second antenna element extends substantially in parallel to a longer cathetus (c1) of two catheti (c1, c2) in the triangle (T).
