Broadband Microstrip Antennas The gain of the antenna is dB. In comparison with the CMSA of radius a = 3 cm, the resonance frequency of the SCMSA is nearly same, but its BW is MHz, which is smaller than the MHz BW of the CMSA. This is because of the larger impedance variation due to its half the area as compared to CMSA.
This antenna is composed of concave cylinder, four shorting inductive posts, a top plate, and backed cavity, and achieves a wide impedance bandwidth from to MHz.
Indeed, a 5-dB increase in simulated gain was noticed when moving the antenna from to cm away from the body model.

The space-based system would detect the exhaust plume from the burning rocket motor of. The gain pattern is normally defined relative to the main beam boresight gain. The boresight is defined as the direction the antenna is intended to point.
This is almost always the direction to which the antenna has its maximum gain, either for transmission or reception. This gain pattern is a.

A little improvement of impedance is obtained in our case. Again the total six-element antenna dimension is less for our case, λ than the other two cases.(λ , λ ) and definitely will be helpful for the design of antenna in VHF range.
The gain obtained in our case is almost double than the other two cases given here. This book, Ultrawideband Antennas: Design and Applications authored by Daniel Valderas and his colleagues Xiaodong Chen, Cong Ling, Juan Ignacio Sancho and David Puente, is a timely collection of the latest progress in the antenna designs, not only for UWB, but also for broadband applications.
