Abstract
A differential antenna structure configured to connect to an electronic circuit having differential inputs and output. The antenna structure includes differential feeding points which are connected to the electronic circuit differential inputs/outputs through capacitors thus eliminating the need for baluns. The antenna structure is also configured to connect to multiple differential inputs/outputs thus eliminating the need for a separate antenna for each differential input/output included on an electronic circuit chip set. The antenna structure can include feeding arms which act as differential feeding points. The antenna can also include tongues for adjusting the capacitive part of the antenna to allow for 1 to n frequencies. The antenna can comprise multiple antenna elements in various arrangements and configurations.
