Problems solved by technology

In a multi-band antenna, the radiation pattern for the higher frequency bands may be distorted due to resonances created in the radiation pattern designed to radiate at the lower frequency bands
This resonance may affect the performance of the high-band radiating element and / or the low-band radiating element of the multiband antenna

Abstract

A first frequency band radiating element configured to operate in a first frequency band may be designed to reduce distortion associated with one or more second frequency band radiating elements configured to operate in a second frequency band. The first frequency band radiating element may include a first printed circuit board. The first printed circuit board may comprise a first surface comprising a first feed line connected to a feed network of a feed board of the antenna. The radiating element may also include a second surface opposite the first surface. The second surface may include one or more first conductive planes connected to the ground plane of the feed plate; and one or more first open-ended traces coupled to the one or more conductive planes.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 116,332, filed February 13, 2015, the contents of which are hereby incorporated by reference in their entirety. Background technique [0003] Various aspects of the present disclosure may relate to base station antennas, and more particularly, to dipole antenna elements of base station antennas. [0004] Multi-band antennas for wireless voice and data communications are known. For example, a common frequency band for Global System for Mobile Communications (GSM) service may include GSM 900 and GSM 1800 . The low frequency band in a multi-band antenna may include the GSM900 band, which may operate in the frequency range of 880-960 MHz. The low frequency band may also include additional spectrum, for example in the frequency range of 790-862 MHz. [0005] The high frequency band of the multi-band antenna may include the GSM 1800 frequency ba...
