1. An antenna with increased radiation efficiency, gain, and directivity, comprising:
- an antenna designed to operate in at least one band of frequency, wherein the antenna is formed on a substrate; and
a reflector for each band of frequency the antenna is designed to operate in;
wherein the reflector is positioned relative to the antenna to redirect electromagnetic radiation of the antenna away from being affected or absorbed by surrounding materials or objects.

Abstract
An antenna having at least one reflector for improving radiation efficiency, gain, and directivity is disclosed. The antenna may be formed on a substrate or be a standalone conductive material that is designed to operate in at least one band of frequency. The antenna includes a reflector for each band of frequency the antenna is designed to operate in. The reflector is positioned relative to the antenna to redirect electromagnetic radiation of the antenna away from surrounding materials or objects that affect, i.e., reflect, refract, diffract, absorb and scatter the antenna'"'"'s electromagnetic radiation.

33. A method of optimizing antenna performance, comprising the steps of:
-
positioning a reflector relative to an antenna in a wireless communication device to redirect electromagnetic radiation of the antenna away from surrounding materials or objects that affect or absorb the electromagnetic radiation; optimizing the distance of the positioned reflector to the antenna to achieve maximum radiation efficiency; and varying the arm lengths of the antenna based on the antenna frequency band of operation and size constraints of the wireless communication device to achieve maximum antenna performance.
