This paper presents design and simulation of an ultra wide band antenna for Customer Premise Equipment (CPE) in the TV White Space (TVWS) spectrum band operating between 420 MHz - 1040 MHz. Integrated, lightweight and wideband antennas have received much attention following the development of wireless communications. The M-shaped monopole is a lightweight, wideband antenna suitable for integration. The size of the antenna has been reduced by using a T-shaped ground plane. The wide bandwidth and reduced size of this antenna makes it desirable for use in TVWS CPE communication systems. The antenna elements are designed on low cost FR4 substrate with ε r = 4.4 and tanδ = 0.02. The M-shaped monopole is fed by a 50 Ω microstrip line. Total volume of the antenna is 198.32 × 111.11 × 1.6 mm 3 . The antenna shows an impedance bandwidth for VSWR ≤ 2 in the frequency range of 420 MHz - 1040 MHz. The gain of this antenna is between 2.24 dB to 4.8 dB in the entire band of operation. The radiation pattern is omnidirectional in both E and H-planes. Radiation and total efficiency of the simulated M shaped monopole antenna achieved is approximately 99 %.
