Abstract:
Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a circuit board and an antenna having a ground element disposed on the circuit board. A ground-extension bracket is coupled to the ground element and oriented orthogonally to the circuit board. The antenna further includes a radiating element disposed on the circuit board and oriented linearly with respect to the ground-extension bracket. The antenna, in response to a radio frequency (RF) signal, is configured to radiate electromagnetic energy in a radiation pattern at an angle of polarization with respect to a plane of the circuit board, where the angle of polarization is acute and angled towards the ground-extension bracket.
