annular slot antenna proposed in [23] provides dual-band feature with two concentric slot-rings and stable radiation pattern in both bands, but the dimensions of the cavity were too large, hence resulting in a bulky structure unsuitable for array design. In this paper, a compact dual-feed dual-band slot antenna is described. It has been ...

CPW Fed Monopole Antenna for Future UWB Diversity Application ... CPW Fed Monopole Antenna for Future UWB Diversity Application written by Jasni A , Jaseem A N published on 2018/04/24 with reference data and citations Dual-Band Microstrip Patch Antenna for Wireless Applications Keywords: Microstrip, dual-band, wireless, wide-band, slot-loaded Abstract A small wideband microstrip patch antenna is introduced. The antenna is designed to function in the 5-6 GHz wireless LAN bands. It achieves multi-band functionality through the addition of a slot to a square patch (21 mm by 21 mm by 2.6 mm). A Broadband Multi-layer Dual-polarization Slot Antenna Based ... The rectangular wide-slot slot antenna in [2] achieves a return loss bandwidth of 35%. When using circular slot or elliptical slot, the wideband effect of the rectangular wide slot antenna can also be realized. In [3,4], a rounded microstrip line feeds a circular slot antenna, and through
L-BAND ANNULAR SLOT ANTENNAS. M.E.C.’s c390-152 L-band annular slot, flush-mount antennas feature an omni-directional azimuth pattern and high peak power handling capability. Its radiation pattern and gain are similar to a matched quarterwave monopole. This antenna meets MIL-A-25707 and is designed to IFF and/or TACAN applications.
Abstract A compact dual-band MIMO/diversity antenna is presented with J-slot suitable for 2.45/5.80 GHz WLAN applications in handheld devices. ON THE Radiation Pattern OF THE L-Shaped WIRE Antenna - PDF The schematic representation shows that the radiation pattern in the ϕ =0 and ϕ =90 planes is a combination of E ϕ and E θ components, produced by each radiating arm.
