WTC engineers have significant expertise on embedded antenna designs and applications. We can work closely with you to ensure the requirements are met, and optimise the WTC's antenna performance when installing on your application. Upon customer requested, max. 5-digit code is allowed. CONTACT INFORMATION Radiation Pattern and Gain were dependent on measurement board design. Walsin's LTCC chip antenna is an electrically small antenna (size smaller than 1/10). The specification of RFANT7635110A1T series chip antenna was measured based on the PCB size and installation position as shown in the figure at table-1.
