An increasing number of wireless communication standards as applied to a device and a trend towards ever smaller, slimmer and lighter devices may cause major design challenges for antenna or antennas (hereinafter referred to as antenna in this document). The antenna represent a category of components that may fundamentally differ from other components in the device. For example, the antenna may be configured to efficiently radiate in free space, whereas the other components are more or less isolated from their surroundings.
Impedance matching or antenna matching, for example, in antenna designs is typically implemented to remove a mismatch loss. That is, a power reflected from a load or the antenna to a power source is minimized while the power that is delivered to the load or the antenna is maximized. In this example, a power detection is implemented to measure transmission power, transmission losses, and the like, in a circuitry of the device.
