Geometric and Design Wideband Antenna for Telemetry devices -- 2

For this project, I am looking for someone to create a high-performance wideband antenna with a frequency range of 1-2 GHz. I have a general idea of the size and form factor for the antenna, but am open to suggestions, depending on design considerations. This antenna will be used for remote monitoring of telemetry devices. The person hired for this project should have experience designing antennas for similar applications, and be capable of providing a realistic timeline for the completion of the project
the project should be used in CST Microwive studio (design & simulation)
In terms of gain, the wideband antenna achieved an average gain of 6 dBi at 2 GHz with a peak gain of 7 dBi at 1 GHz.
