Automated antenna trim for transmitting and receiving semiconductor devices
First Claim
1. A method of tuning an antenna of a radio frequency communication device, the method comprising:
- evaluating an antenna response to at least one test signal; and
in response to an evaluation result;
accepting the radio frequency communication device when the evaluation meets a first criteria;
rejecting the radio frequency communication device when the evaluation result meets second criteria;
coupling an antenna segment to the antenna using an antifuse when the evaluation result meets third criteria; and
detaching an antenna segment from the antenna using a fuse when the evaluation result meets fourth criteria.

Abstract
A radio frequency communication device and methods of testing and tuning an antenna attached thereto are disclosed. A radio frequency communication device comprises internal circuitry and an antenna having a plurality of antenna segments associated therewith. Each antenna segment is associated with the antenna in either series or parallel relation through at least one of a fuse and an antifuse. In testing and tuning, a comparison is made to indicate whether the antenna is too short or too long. If the antenna is too short, an antenna segment may be attached to the antenna by initiating an antifuse. If the antenna is too long, an antenna segment may be detached from the antenna by blowing a fuse. If it is indeterminate whether the antenna is too short or too long, an antenna segment may be either attached or detached, the test repeated, and the results of the repeated test compared with the prior test to determine whether the correct action was taken.

13. A method of testing a radio frequency communication device comprising:
-
comparing at least one characteristic of an antenna response to at least one test signal with at least one specification value; and initiating a fuse blow sequence to detach an antenna segment associated with an antenna when the comparison yields a first criteria and initiating an antifuse initiation sequence to attach an antenna segment associated with the antenna if the comparison yields a second criteria. - View Dependent Claims (14, 15, 16, 17, 18)
