Abstract In this paper, we have presented the simulation results of a rectangular microstrip patch antenna at terahertz (THz) frequency ranging from 0.7 to 0.85 THz. THz electromagnetic wave can permit more densely packed communication links with increased security of communication transmission. The simulated results such as gain, radiation efficiency and 10 dB impedance bandwidth of rectangular microstrip patch antenna at THz frequencies without shorting post configuration are 3.497 dB, 55.71% and 17.76%, respectively, whereas with shorting post configuration, corresponding parameters are 3.502 dB, 55.88% and 17.27%. The simulation has been performed by using CST Microwave Studio, which is a commercially available electromagnetic simulator based on the method of finite difference time domain technique. Keywords THz electromagnetic spectrum . Microstrip patch antenna . Bandwidth . Photo- conductive antenna and microstrip-line.
1 Introduction Development of the next generation wireless communication network requires systems with extremely broadband capabilities in high mobility environment. For such applications, range from personal communications to home, car and office networking, high data rates, high spectral efficiencies and stronger fading mitigation have to be achieved. Due to its particular role, the microstrip antennas simultaneously satisfy stringent requirements concerning geometrical characteristics (small-size, light-weight, adaptability to actual platform and non-obstructive to user), electrical performance (wide-bandwidth, radiation properties, high-efficiency, reconfigurability and suitability for diversity) and manufacturing constraints (low-cost, reliability, packaging capabilities) as well as the performance must not be degraded by environment and design must satisfy radiation safety standards.

The frequencies higher than microwaves offer many advantages for wireless communication technology, including broad-bandwidth for high data rate information transmission, improved spatial directivity and resolution, low transmission power, and low probability of interference/interception with system compactness. THz electromagnetic spectrum is very useful for the communication, which will satisfy most of the aforementioned requirements. This electromagnetic wave spectrum is of increasing interest to service provider and system designers also because of extremely broad bandwidth available for carrying communication information and relatively free of spectrum users. Among the practical advantages of using THz r
