Abstract: In this paper, a novel design of low profile printed slot antenna using wideband artificial magnetic conductor (AMC) is presented with improved radiation performance. For this purpose, the radiating slots with three unequal arms fed by coplanar waveguide are employed for broadening the impedance bandwidth with three resonances.
High gain waveguide slot array antenna for 60 frequency, defines the bandwidth of the antenna.It is well known that adding iris in the waveguide improve the matching at least over a narrow frequency band, here the 4-slot array (rectangular slots) with one added iris is simulated for different iris length i_l and positions i_p. Enhanced-bandwidth PIFA Antenna with a Slot... -… Design of Dual Frequency Notched Semicircular Slot Antenna with.Especially, the bandwidth of the high band is improved even significantly when S increases from 50 mm to 70 mm. The above study indicates that the optimal performances of the low and high bands are highly dependent on the slot... Gain Enhancement of a Wide Slot Antenna Using Slot antenna Slot antenna with FSS (simulated).A second order, band pass frequency selective surface with large bandwidth combined with a wideband slot an-tenna has been studied and demonstrated successfully.

As a result, the 3 dB ARBW of the proposed antenna is enhanced. Broadband Slotted Coaxial Broadcast Antenna Technology - Dielectric greater degree of azimuth and elevation pattern flexibility. The one disadvantage of slotted coaxial antennas is their inherently narrow bandwidth. In.
bandwidth and to add resonant frequencies. The radiating patch is fed by a coaxial probe at a position (X f, Y f)for excitation of the antenna. The slots’ dimensions, the substrate height, and the excitation point position are used to determine the broadband characteristics of the antenna.
