Abstract

Antenna apparatuses and methods used in wireless communication devices are disclosed. The antenna includes a first portion configured to be coupled to a communication device. The antenna also includes a second portion configured to be coupled to the first portion. The first portion and second portion are coupled by overlapping the first portion and second portion so as to produce an omnidirectional radiation pattern and a vertical radiation pattern.

Claims (11)

1. An antenna used in a wireless communication device, the antenna comprising:

a first portion, wherein a first end of the first portion is configured to be coupled to a communication device; and

a second portion, wherein a first end of the second portion is configured to be coupled to a second end of the first portion,

wherein the first portion and second portion carry current of equal amplitude and are coupled by overlapping close proximity coils of the second portion and first portion over the respective first end of the second portion and the second end of the first portion such that a progressive phase difference between the first portion and second portion is a quarted wavelength so as to produce both an omnidirectional radiation pattern and a vertical radiation pattern.

2. The antenna of claim 1 , wherein in coupling the first portion and the second portion, the antenna is operable to be excited with the progression phase difference between the first and second portions to emit radiation in a direction of a radiation element null of the first portion and second portion.

3. The antenna configuration of claim 1 , wherein the first portion is a monopole antenna.

4. A method for configuring an antenna used in a wireless communication device, comprising:

coupling a first end of a first portion of the antenna to a communication device; and

coupling a first end of a second portion of the antenna to a second end of the first portion,

wherein the first portion and second portion carry current of equal amplitude and are coupled by overlapping close proximity coils of the second portion and first portion over the respective first end of the second portion and the second end of the first portion such that a progressive phase difference between the first portion and second portion is a quarter wavelength so as to produce both an omnidirectional radiation pattern and a vertical radiation pattern.

5. The method of claim 4 , further comprising exciting the antenna with the progression phase difference between the first and second portions to emit radiation in a direction of a radiation element null of the first portion and second portion when coupling the first portion and the second portion.
