A novel design of hybrid microwave bandpass filter using lumped element and microstrip line technology

A Triple band Microstrip Antenna with Enhanced Bandwidth for Radar Applications

“…A triple band micro strip antenna is proposed in this paper. The antenna is improved from its last structure [1]as in that it was working for six different bands while their bandwidth was not good, so this new structure shows three bands working for various applications as the bands have wide bandwidth. The structure has two rectangular hollow patches and one stub in each rectangular patch.…”

“…The corresponding frequency vary is three hundred MHz to 300 gigahertz. This spectrum is restricted and needs to be shared, thus the demand for top performance RF/Microwave circuits is increasing that have high property and constant information measure is bit by bit increasing [1].In recent years, the shrinking of antennas has become additional and additional necessary thanks to the increasing demand for little antennas because the fast development in wireless communications [2].The advantages of microstrip antennas build them well-liked in several wireless communication applications like satellite communication measuring instrument, medical applications, aircraft, spacecraft, and missile applications at identical time disadvantages of Microstrip antenna is slender information measure, poor potency [3].…”

Component value calculations in a mixed element ladder network containing series capacitors separated by unit elements

“…The objective in Juliet et al 4 is to design and implement a hybrid microwave band-pass filter (BPF) by mixing two technologies such as microstrip line and lumped element and evaluate its performance. It is shown that the designed hybrid BPF has an improved performance and has reduced size compared with a filter designed using individual lumped and microstrip components.…”
