N2 - A novel TMz 101 broadbeam acute isosceles triangular dielectric resonator antenna is presented. The antenna is fed by a wide aperture slot, which simultaneously excites the first two lower order modes. With the help of Mode-I frequency, dielectric resonator height is calculated which is 0.105 λm and plays a key role in yielding wide 3 dB beamwidth radiation patterns. A comparison of broadbeam antenna fed by aperture slot and a probe is made which shows that optimal feed mechanism for broadbeam operation is aperture slot. Then, metal perturbation is introduced within the dielectric resonator at height of 6mm to improve the co- to cross polar isolation by 10 dB. Proposed antenna operates in the frequency band of 2.03 GHz to 3 GHz and yields E-plane beamwidths from 134° to 138° and H-plane beamwidths from 120° to 123°. The antenna is broadbeam in both planes in the frequency band from 2.1 GHz to 2.3 GHz.
