A compact planar inverted-F antenna (PIFA) with single layer dielectric load is presented in this paper. The proposed antenna covers 28 GHz millimeter wave frequency bands and can be useful for future 5G hand held devices. The antenna is placed on a mobile phone substrate of dimensions 110 mm × 60 mm reserving 70 mm × 35 mm for a battery, and occupies a small volume of 4 mm × 4 mm × 1.34 mm. The antenna has a wide operating bandwidth (|S11|< -10dB) of 980 MHz (27.47 - 28.45 GHz) and a peak gain of 8.80 dBi with a gain variation of less than 0.55 dB within the antenna bandwidth. The proposed antenna has stable broadside radiation in yz and xz planes with low side lobe levels of -13.3 dB, -14.4 dB, and wide beamwidths of 66.6°, 64.5°, respectively. Radiation efficiency and total efficiency of the antenna vary between 97% - 99% and 88% - 96%, respectively. Antennas impedance bandwidth, gain, radiation, and total efficiency are assessed with and without a battery.
