Futuristic IoT applications demand antenna designs to fulfill a number of challenging performance metrics. The antennas for such applications must be small to be easily integrate-able with miniaturized devices, have near-isotropic radiation pattern to be able to communicate in an orientation insensitive way, provide sufficient bandwidth (4% for 2.4 GHz WiFi)requisite of concerned communication protocol and be low cost enough to be implemented in billions of devices. Also, as these antennas integrate with the devices in very small spaces, so the effect of components (such as battery, chips etc.)also require consideration in design. This paper presents for the first time, a WiFi 2.4GHz near-isotropic T -shaped monopole antenna additively manufactured on the package. The antenna is designed whilst taking battery and WiFi chip effect into consideration. The maximum gain is 1.78 dBi with a gain deviation of 6.84 dB. The VSRW=2 bandwidth is achieved from 2.4 to 2.7 GHz.
